| explain: |
| GP-01 is flammable for personal useGas detectioninstrumentGP-01 can detect combustible gas mixtures on site and display gas concentrations, providing personal protection for individuals working alone in hazardous areas for extended periods of time This low-energy combustible materialGas detectioninstrumentNi Cad batteries can be used continuously for more than 8 hours and weigh only 3.5 ounces (when loaded with alkaline batteries) The measurement range of GP-01 is 0-100% LEL, and it can display concentration values on an LCD screen with automatic lighting GP-01 can intermittently or continuously detect combustible gases or vapors on site GP-01 has 2-level adjustable preset alarm points: 10% and 50% LEL, and is equipped with sound, light, and vibration alarms. The coin shaped sensor is installed inside a metal envelope with contact plates GP-01 can be safely used in hazardous areas and has obtained intrinsic safety certification for Class I, Zone I, Groups A, B, C, and D of the CSA standards in the United States and Canada. GP-01 has been tested and passed the CSA C22.2 NO.152 standard |

| working principle: |
|
The coin shaped sensor is installed inside a metal envelope with contact plates, and the detection of combustible gases occurs on the active elements on the surface of platinum. When any combustible gas or vapor in the air is heated on the surface of the active elements, it will catalyze oxygen (relying on oxygen in the air). This oxidation process generates heat, increases the temperature of the active element, and increases its resistance. In the same environment, a similar element without catalyst (active element) is connected on the adjacent side of the Wheatstone bridge. When the resistance changes, this bridge will generate a current output corresponding to the gas concentration. This current output is amplified on the resistance of the instrument, displaying a reading of% LEL. When the reading exceeds the preset alarm point, an alarm will occur.
