Digital MEMS Inclinometer System

Digital MEMS Inclinometer System Portable

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

Description

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.
