This combustible gases leakage detector adopts high precise sensors, convenient for users to safely detect and test a variety of combustible gases types, easy to meet different test needs. It can automatically matching the appropriate color backlight and change concentration simulation bar according to the measured concentration, and with green and red backlight for more intuitive displays. With low battery indicator function. Widely used, suitable for water heating device detection, gases pipeline detection, industrial waste gases detection, gases pipeline detection, oil station operation, gases leak detection, etc. Features: Compact Size: Portable gases detector, compact ABS body, fallproof and dustproof, quick response, detect leaks quickly. High Precise Sensors: Using quality gases-sensitive semiconductor sensor, with fast response and react very quickly, support more accurate measurement. LCD Display with Backlight: 1.1inch color LCD display with backlight, with clear definition, you can see the data clearly. It can automatically matching the appropriate color backlight and change concentration simulation bar according to the measured concentration, and with green and red backlight for more intuitive displays. Easy to Use: Convenient for users to safely detect and test a variety of combustible gases types, easyto meet different test needs. Measurable Gases Types (partial list): Can detect a variety of gases, methane, natural gases, ethanol, gases, propane, benzene, ethylene oxide, hexane, n-butane, acetylene. Sensitivity Adjustable: High and low sensitivity adjustable, you can first choose high sensitivity to sense the general ranges, and then choose low sensitivity to accurately determine the air leakage point. Sound&Light Alarm: Sound and light prompts, when detecting combustible gases sink leakage, the meter beeps, the backlight will turn to red, and the concentration simulation bar increases. Multifunctional Design: With low battery indicator, data hold, automatic shutoff, on/off test, and auto CLR clear function. Wide Applications: Suitable for water heating device detection, gases pipeline detection, industrial waste gases detection, gases pipeline detection, oil station operation, gases leak detection, etc. Specifications: Name: Combustible Gases Detector Material: plastics Color: black, white (optional) Battery: 2 * 1.5V AAA battery (not included) Display: color LCD disply with backlight Sensor: gases-sensitive semiconductor sensor Test ranges: 50-1000PPM Response sensitivity: 50PPM Response time: 500PPM about 2s Detecting gases: combustible gases Test Gases (partial list): ethanol, propanol, acetylene, ammonia, benzene, methane, alkane, propane, butane, epoxy butane, gasoline, emulsion gases naphtha natural gases, paint thinner gases Use environment: 0-50, 20-80%RH Storage environment: -10 to 60, 20-80%RH Item size: 134.5 * 32.5 * 16mm / 5.30 * 1.28 * 0.63in Item weight: 50g / 1.76ounce Package size: 145 * 40 * 20mm / 5.71 * 1.57 * 0.79in Package weight: 70g / 2.47ounce Packing List: 1 * Combustible Gases Detector 1 * Guideline
