HABOTEST HT56Pro Highly Sensitive Natural Gas Detector Pen Type Leakage Alarm with Audible and Visual Alarms Sniffer for Detecting Combustible Sources like Methane and Acetone Perfect for Home

The HABOTEST HT56 Pro Combustible gas detector is a highly functional and reliable device, featuring a stylish black red color combination and a durable ABS construction.It is equipped with an LED LCD screen that provides clear and easy-to-read displays. The detector utilizes a gas sensitive semiconductor sensor, which requires a warm-up time of approximately 30 seconds.When it comes to its detection capabilities, for methane, the response range is about 1%LEL (100PPM) to 10%LEL (5000PPM), and the reaction sensitivity is about 1%LEL (100PPM). It can detect a wide variety of gases including acetone, acetylene, alcohol, ammonia, benzene, butane, ethanol, ethylene oxide, gasoline, hexane, hydrogen, methane, naphtha, natural gas, paint thinner, propane, solvents, and many others.The device has an automatic shutdown feature. If there is no measurement signal or button operation for about 5 minutes, it will automatically turn off, conserving battery power. There is also a low battery indicator. When the battery symbol on the LCD lights up, it indicates that the battery voltage is low, and it is necessary to replace the battery promptly to ensure normal detection.It comes with a dual-color backlight, enhancing visibility in different lighting conditions. Sensitivity selection is available, allowing users to switch between high and low sensitivity modes. In the high sensitivity mode, the alarm starts at about 1% LEL (100ppm), while in the low sensitivity mode, the alarm starts at about 3% LEL (1500ppm). The alarm mode includes both a buzzer and display, providing clear alerts.The response time varies depending on the gas concentration. For concentrations ≤500PPM, it is about 5 seconds, and for >500PPM, it is about 2 seconds.The HT56 Pro can operate under working conditions of 0℃ to 50℃ and 20% to 80%RH, and can be stored under storage conditions of -10℃ to 60℃ and 20% to 80%RH. Powered by 2 X 1.5V AAA alkaline batteries, it is a convenient and useful tool for accurately detecting combustible gases in various environments.it serves as an ideal Thanksgiving or Christmas gift for family and friends.
