Distance Measuring Instruments
Our collection of distance measuring instruments, or DMIs, can accurately record distance and data using various types of sensors and GPS coordinates, which can then be transferred onto a report document and even presented visually on Google maps. Call us today and view our devices below for more information about distance measuring instruments.
​
RAC SERIES: DMIs
Accurate, reliable and easy to operate, our RAC units are the industry standard Distance Measuring Instrument (DMI). These cost-effective units save time and money by allowing personnel to measure distance, accurate up to 1 foot per mile, while driving as fast or slow as necessary.
RAC Geo II
On-board GPS distance measuring, coordinates and data memory.
No Calibration. No Installation. No External Sensor.
RAC Plus I
Highly accurate, vehicle installed, distance measuring.
Use a magnetic sensor or OBD AutoLink sensor to install into vehicle.
DISTANCE SENSORS
Distance sensors read and modify the data coming from your vehicle and send a signal to the DMI telling it when to count distance.
There are currently two types of distance sensors that can be used:
MAGNETIC
The Magnetic Distance Sensor uses the oldest technology of all the sensors, but when properly installed, remains the most accurate.
This sensor works in any vehicle..
AUTOLINK OBD
You plug the AutoLink II into the OBD interface on your vehicle, then plug the AutoLink Pro into your RAC's power port using the provided telephone-style cable. That's it. No getting under the hood, no splicing wires, no tools required.
