1. Lcd high-definition color screen: The color lcd displays changes in gas solubility, with a high brightness display screen that is clearly visible in different lighting environments. 2. Multiple alarm reminders: When abnormal solubility is detected, sound and light alarms are triggered, and the screen dynamically reminds. 3. Metal universal probe tube: Can flexibly adjust the curvature, suitable for special scenarios and narrow leakage detection. 4. High sensitivity sensor: Accurate measurement, fast response, and high sensitivity. 5. Widely applicable scenarios to meet detection needs: Widely used in petroleum and petrochemical, natural gas, gas pipelines, kitchen gas, catering and hotels, etc. Product name: combustible gas leak detector Display: color lcd display Working voltage: dc3v Working current: ≤150ma Detection range: 0~10000 ppm Resolution: 1ppm Applicable gases: , methane Response time: T Less than 30s Working environment: storage temperature -40℃~85℃ Working temperature: -40℃~70℃ Working humidity: ≤95% rh, no condensation Detectable gases: natural gas, liquefied petroleum gas (lpg), carbon monoxide (co), methane (ch4), ethane (c2h6), propane (c3h8), ethylene (), propylene (c3h6), acetylene (c2h2), propyne (c3h4) Power supply: 2 x AAA batteries (Not included batteries) Color: Black Material: ABS Package Contents: 1 * Portable Combustible Gas Detector Only the above package content, other products are not included.
