Feature:1. HIGH SENSITIVITY: The gas leak detector has high sensitivity and test accuracy for combustible gas detection, ensures safety.2. RAPID RESPONSE: The probe of the gas detector is ten hole airway design, allows rapid gas inflow and rapid response.3. WITH LIGHTING: The test probe is designed with high brightness light, which can be turned on in dim scenes, more convenient and practical.4. VA HD COLOR DISPLAY: VA ture color display screen has analog bar and digital display modes, more clear and intuitive for observation.5. WIDE PURPOSE: The combustible gas detector can detect the leakage of combustible gas in the pipeline, equipment, regulator.Specification:Item Type: Combustible Gas DetectorMaterial: ABSColor: Black and redMeasuring Range percent LEL: 0-20 percent , PPM: 0-9999PPMResolution: percent LEL: 0-20.0 percent (0.1)PPM: 0-999PPM(0.1), 1000-9999PPM(1)Accuracy: 10 percent F.S.
