The DP-IR functions by using an infrared optical gas detection system. This instrument is intended to replace the current surveying equipment using the traditional Flame Ionisation method with next generation technology utilising an infrared light beam, eliminating the need for expensive gas cylinders and refill systems. It is designed to be highly selective to detecting methane gas only, and will not false alarm on other hydrocarbon gases.
The DP-IR operates under a variety of field conditions including cold and hot temperatures. Its rugged design will stand up to normal field use and operating conditions.
The DP-IR has a built-in Self-test function that will verify the instrument is operating properly. Using the internal calibration cell, the operator performs the self-test as part of a daily start-up routine. While in operation, the DP-IR continuously monitors several internal parameters to ensure that it is functioning properly. Should any of these parameters go outside of operational limits, a constant audible alarm will sound and an ERROR icon will be displayed.
