【0 -9999PPM Gas Leak Detector】Neoteck natural gas detector precisely pinpoints leaks of various combustible gases like methane, natural gas, and propane. Its high accuracy ensures swift identification of potential hazards, enhancing safety measures for home inspector ,motorhome owner,engineers, technicians and lab personnel 【Accurate Measurement】With a measurement range of 0-9999PPM/0-20%LEL, propane leak detector allows unit switching and zeroing data. Its ±10% methane testing accuracy and quick response time of 2s for concentrations above 500ppm ensure reliable and efficient gas detection 【3 Sensitivity Modes】The sensitivity of combustible gas detector can be customized by long-pressing the “sens key” to select H/M/L sensitivity alarms. Low sensitivity mode triggers an alarm ≥10.00% LEL (5000 PPM), medium sensitivity mode ≥5.00% LEL (2500 PPM), and high sensitivity mode ≥1.00% LEL (500 PPM).This feature offers flexibility and accuracy, triggering alerts based on different concentration levels for optimal safety measures 【12” Flexible Gooseneck Probe】Featuring a 12-inch flexible gooseneck probe, Neoteck natural gas leak detector allows easy access to hard-to-reach areas such as natural gas pipelines, propane tanks, gas fireplaces, and more. Its versatility enables convenient leak detection in narrow spaces, both indoors,outdoors and rv 【Audible and Visual Alarm】Equipped with a 70dB sound alarm and an LCD screen,propane gas detector provides dual alerts for gas concentrations.It can detect gas leakage concentration and display values from 0-9999 PPM/0-20% LEL.At the corresponding sensitivity modes, as the gas concentration increases, the analog bar will change to blue-yellow-red, accompanied by a faster beeping sound.The audible alarm can be silenced by a short press of the sound key 【Humanized Design】Natural gas leak detector conducts temperature and humidity tests with ease, and switch between ℃ and ℉ units. The automatic shutdown feature ensures power-saving, with a 10-minute idle shutdown. You can disable this feature by a short press of the power button, and a long press initiates shutdown when hear a “beep” 【NOTE】(1) Natural gas detector must be powered on in a clean air environment (2) The preheating function ensures accurate sensor readings. Allow portable gas leak detector to preheat at startup for about 30 s. 3 beeps signal completion Specifications:
