Whether you are replacing a broken gauge on a riding lawn mower or tracking service intervals on a portable generator, this device provides industrial-grade reliability.

The non-polarized signal connection terminals mean there is no positive or negative pole confusion, ensuring a fast and error-free setup. Built for extreme outdoor environments, the internal components are fully sealed with a 100 percent epoxy resin construction. The rigorous IP68 waterproof rating ensures accurate data logging even during heavy rain storms, mud exposure, and high-pressure equipment washing. A built-in CR2050 backup battery safeguards all timing data during power outages or when the engine is turned off.
