We relentlessly perform R&D activities to innovate global-leading diagnostic precision instruments, flexible interconnect electronic components and smart locking devices contributing to the advancement of various industry clusters such as automotive, aerospace, medical, off-shore, semiconductors and consumers electronics. In 2009, Digi-Pas® pioneered the world's-first dual-axis precision digital level and in 2011, we further pioneered the world's-first 2-axis intelligent machinist level that have greatly simplified any high precision machine levelling and planar angle measurements tasks. In 2012, we sustained our innovation by presenting the world-first Digi-Pas® 2-axis ultra-precision inclinometer in Tokyo.

As Leveling and angular measurements are vital functions for most precision equipment installation, machine alignments and metrology in many industries within the precision engineering cluster, engineers are often constraint by using traditional spirit bubble levels or single-axis inclinometers to accomplish these basic tasks. Further, precision leveling/alignment tasks often involve planar i.e. 2-dimensional surface (i.e. 2-Axis), while traditionally leveling instruments are limited to single axis, Digi-Pas has empowered many engineers and eradicated constraints associated with using single-axis instrument that requires them to conduct leveling tasks one axis at a time and very time-consuming yet tedious and unproductive trial-and-error iterations. Digi-Pas® technology and innovation effectively resolve these disadvantages offering ACCURATE, PRECISE & FAST leveling and angle measurements which traditional single-axis inclinometers and spirit 'bubble' levels are unable to match.

In 2014, we launched eGeeTouch® NFC smart locking device utilizes state-of-art proximity access security technologies was the world's first of its kind and received numerous Innovation Awards from in Japan and USA. These smartlocks effectively resolve the disadvantages associated with conventional locks while providing enhanced security as well as a truly hassle-free experience.

Advantages of using Digi-Pas® 2-Axis precision digital inclinometer over conventional single-axis levelling instruments:

Traditional spirit 'bubble' level, pendulum-based or servo-driven digital levels and inclinometers were often constrained with (i) single axis, (ii) narrow angle measurement range, (iii) large footprint/size and (iv) inability to withstand high shock/impact. Single-axis inclinometer is also susceptible to cross-axis error particularly when measuring at larger angles and at higher precision. However, precision levelling, angle measurement, alignment and surface flatness profiling tasks essentially involve 2-dimensional plane rather than two independent orthogonal single-axis lines. Digi-Pas® 2-Axis precision inclinometer utilizing advanced MEMS technology provides simultaneous 2-axis and wide angle measuring range capabilities that traditional single-axis digital/'bubble' levels are unable to offer.

  • 2-axis MEMS technology enables simultaneous 2D (X-Y plane) leveling and angles measurement instrument (i.e. pitch & roll), completely eliminates tedious trial-and-error (i.e. going back-and-forth taking reading one-axis at a time) experienced when using single-axis levels to align precision machines/objects. No costly need for owning 2 units of single-axis digital levels to do the same task as one unit Digi-Pas® dual-axis. i.e. effective & time saving. The repetitive yet monotonous trial-and-error activity of using single-axis levels is also time-consuming, non-productive and promote boredom that often succumb engineers to resort for compromising works.
  • Digi-Pas® 2-axis MEMS driven inclinometers are compensated and calibrated for non-linearity and operating temperature variation utilizing proprietary advanced manufacturing patented processes. Angular accuracy and stability performance over a very wide measurement range are externally verified by accredited 3rd party independent certification bodies traceable to NIST, UKAS, DIN & JIS. i.e. accredited & reliable. Because of its 2-axis, wide angular measuring range and vibrometer functions, Digi-Pas® inclinometer is more than just a leveling tool. It is an instrument that provides a comprehensive solution for planar angular leveling, measuring, diagnostic and alignment needs.

Three-Point Contact Base of Digi-Pas® 2-axis Precision Inclinometer


  1. Limitations of conventional rectangular contact base levelling instrument

    The contact base surface finish quality of a typical conventional leveling instrument or inclinometer is one of the critical determinants of its accuracy performance and the common rectangular-shape flat surface often suffers from geometrical deviation resulting from:

    • Waviness and unevenness
    • Irregularities due to distorted or worn surface
    • Dust and dirt trapped or surface roughness

    Figure 1 illustrates three typical poor surface finishes of conventional rectangular surface contact base. The unstable surface-to-surface contact causes rocking which results in measurement inaccuracy derived from inconsistent readings. A common practice to improve the outcome under such constraint is by taking more samples to obtain an averaged reading. However, this time-consuming and repetitive activity often promotes boredom that succumb engineers to resort for compromising works, especially when the instrument is located at some distance.

    Although high quality surface requires both flatness and smoothness, it is difficult and expensive to control in machining of metal alloy surface particularly when involving relatively large area. Increasing the flatness and smoothness of a few microns would usually increase exponentially on its manufacturing costs. This often results in a trade-off between the manufacturing costs of the instrument and thus compromises its accuracy performance.

    In addition, the rectangular contact base surface of a conventional leveling instrument is also susceptible to target measuring surface unevenness, which is another factor affecting levelling and measurement accuracy. Figure 2 illustrates issues associated when a rectangular contact base of a traditional single-axis spirit level is placed on a typical machined surface having low frequency, long wavelength flatness variation. It is clearly shown that full and stable surface-to-surface contact could not be achieved between the instrument base and the measuring surface. The contact may cause rocking that results in measurement errors, hence affects the accuracy and reliability of the leveling outcome.

  2. Pioneering the application of 3-point contact base in 2-axis precision levelling instrument

    In view of the constraints inherent in conventional contact base measuring instrument described in the foregoing, Digi-Pas® pioneered and patented the utility of 3-point contact base for its 2-axis precision angular and surface flatness measurement instruments. The triangular shape of 3-point contact base seeks to address the shortcomings associated with conventional rectangular contact base.

    Figure 3: Stable 3-point-to-surface contact between Digi-Pas® inclinometer and flat surface object

    Figure 4: Stable 3-point-to-surface contact between inclinometer and uneven surface
    Figure 4: Stable 3-point-to-surface contact between inclinometer and uneven surface

    When a 3-point contact base leveling instrument is placed on either flat or uneven surface object (e.g. typically machined metal surface) as shown in figure 3 and 4 respectively, the three-point frame serves as a triangle-plane platform for supporting the weight and maintaining the stability of the instrument. It provides maximum stability and strength against downward forces and horizontal forces as well as movements about horizontal axes. With the sturdy three-point stand, a most stable 3-point-to-surface contact can be established without rocking and thus achieving consistent leveling readings of the two-dimensional measuring surface. Any angular deviations on the surface area is detected by Digi-Pas® 2-axis inclinometer as sensitive contact points touch on a particular section of uneven surface area.


  3. Advantages of Digi-Pas® 3-point contact base levelling instrument

    In 2009, Digi-Pas® pioneered and patented the utility of 3-points contact base to its world-first 2-axis precision digital level series that effectively prevent any surface dimensional deviation caused by unevenness of its own instrument’s metal surface contact base. Figure 5 illustrates the 3-point contact base screws made of harden steel and titanium materials that offers great stability and prevent it from ‘rocking’ when placed on either flat or uneven smooth surface for 2D levelling and planar angular measurement.

    Figure 5: Digi-Pas<sup>®</sup> patented 2-Axis Precision inclinometer utilizing 3-Point Contact Base
    Figure 5: Digi-Pas® patented 2-Axis Precision inclinometer utilizing 3-Point Contact Base

    Maintaining the 3-points contact is easy, speedy and cost effective simply by replacing the harden/titanium screws whenever they wear off, saving significant amount of time and cost as compared to maintain the instrument’s contact base surface finish through standard machining. Device accuracy performance can also be re-calibrated by performing User Self-Calibration or “Absolute Level” setting at ease. Please refer to user manual for detail instructions.

    For using Digi-Pas® 2-axis inclinometer to level an object having a very rough top surface, the 3-point harden/titanium screws can be temporarily removed and use the flat base surface to naturally average the rough surface. Absolute Level Setting is required to be performed immediately after changing the base to ensure the instrument maintains its reference accuracy. However, in high precision leveling, angular measurement and surface profiling tasks usually involve high quality flatness and smooth surfaces such as granite and metal alloy machined surfaces. Hence, 3-point contact base is a better choice.
