Portable Gas Leak Detector

The STMOUTUO HT61 is a pen-style gas leak detector designed for use in RVs and homes. It detects combustible gases including propane, methane, natural gas, coal gas, gasoline, LPG, and LNG. The device features high and low sensitivity modes, entering high sensitivity with a range of 50 to 500 ppm after a 30 to 45 second warm-up. Visual and audible alarms activate when gas is detected.

For Spot Checks Not Fixed Monitoring

This detector suits owners who need a portable tool for periodic leak checks around appliances, pipework, or RV systems. The backlit LCD screen and simple three-button operation make it accessible for non-technical users. It is not intended for continuous, unattended monitoring or permanent installation where a hard-wired alarm system would be required. Buyers needing automatic shut-off valves or smart-home integration should look at different categories of safety equipment.

Check Detection Needs And Power

Verify that the gases you need to detect are listed among the detectable types such as propane and methane. The unit ships with two AAA batteries included for immediate use, and an automatic shutdown feature activates after five minutes of inactivity to conserve power. Ensure the operating temperature range of the environment matches the device specifications before relying on readings. The package includes a storage bag and user manual for reference.
