TRM-UST is a small diameter, short length probe that can be threaded into the space between the walls of a double wall storage tanks or into a low point well in a double wall pipe system. The probe will detect both fuels leaks (diesel, jet, gasoline or crude oil) and ground water intrusion into the interstitial space. Depending on monitoring option there are combined or separate signals for water / fuel detection.
TRM-UST is approximately 5/8" diameter x 3" long. All probes comes with 32 ft of leader cable.
Monitor with TRM-Easy5-Panel or TRM-Easy5-Relay for UL/CSA approved dual output relay (fuel/water).
