Digital MEMS Inclinometer System


For measuring any lateral movement down in the earth, via inclinometer casing, the Digital MEMS Inclinometer System from RST Instruments Ltd. was the first, and is still the best, Digital MEMS Inclinometer System available

Product Features

  • Can traverse a smaller radius bend (1.9mm) than all other inclinometers
  • The shortest overall length
  • Up to 30 hours of continuous use
  • Can be charged without removing the battery
  • Least amount of connector interference


Since 2003, RST’s Inclinometer systems have had the shortest overall length available for a given base length compared to competitive inclinometers.

With a minimum negotiable casing radius of 1.93 m, RST’s Digital MEMS Inclinometer can still traverse a smaller radius bend than all other inclinometers available in the industry. A local microcontroller in the probe manages data collection, applies precision digital calibration, and provides a fast settling time which results in very efficient data collection.

The RST Digital Inclinometer App functions as the data collector. The app is designed for field personnel to easily configure and collect readings from the inclinometer probe.

Speak with an Expert

I’m very happy with the quality of the instrumentation and technical support from RST, as always. They worked with us from the initial stages of the project to ensure that we were fully prepared and equipped to use the RSTAR network for the first time. They delivered everything within the tight project time frame to ensure that there were no delays on site, and the submersible tilt meters looked like new even after over twelve months of being submerged in Thames water!
