Multi-scene measurement Adopting the main control chip, it has a higher and more stable experience, sensitive/stable/intelligent Place the instrument sensor at the gas tank switch port, and the screen simulation section rises to red with a buzzer alarm indicating the presence of a combustible gas leak When the gas concentration exceeds 20% Ifl safety value,the screen simulation section rises and beeps, the button to turn off/turn on the buzzer Extended bendable hose Using all-metal material, it can be bent arbitrarily, making long-distance detection more convenient Ambient temperature detection:-20.0 to 60.0 (-4.0F to 140.0F) Accuracy:0.0 to 45.0(32F to 113F) 2.0/4.0F Other: +3/6.0F Resolution: 0.1/1 Response time:less than equal 500ppm:about 5 seconds;Less than 500ppm:about 2 seconds Alarm method:Analog segment display,buzzer alarm Automatic shutdown:If there is no operation meter for 10 minutes,it automatically shut down. Cancel automatic shutdown:In the power-on state, place an order and the power button to cancel the automatic shutdown. Sensor:Gas sensitive semiconductor Detection range:50-10000Pm (methane) Response sensitivity: 50ppm(methane) Adjustable sensitivity:High sensitivity/low sensitivity Temperature unit selection:C/F Warm-up time:About (The product printed words depending on the batch, but this does not affect use) Color: As Shown Material: ABS Package Contents: 1 x Combustible Gas Detector Alarm Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
