Easy to Use, Visual and Audible Alarm: Simply insert the included batteries and let the PT177 complete its 30-second self-calibration process, then point it in the direction you think the leak is.

It features five red LEDs (visual) and 75-decibel audible alerts that increase in volume with increasing gas concentration

If idle for 5 minutes without operation or gas detection, the PT177 will automatically shut down. Detection Range: 50 to 1000 ppm (based on methane)
