Wintact WT8823 Combustible Gas Detector

The Wintact WT8823 combustible gas (EX) detector is an instrument for detecting gas leak concentration. It has a high-definition screen that displays the measured values and offers stable performance to ensure safety and reliability. Its small, portable design makes it suitable for checking gas pipelines, exhaust gas and fuel leaks, propane irrigation stations and flammable gas pipelines.

The instrument measures from 0 to 100 %LEL with a contact combustion type sensor and a response time of about 10 s. LEL is the lower explosive limit: the lowest content of a combustible gas in air that results in an explosion. It can be used to test leakage of a variety of flammable gases; the manual lists, as a partial list, natural gas, propane, butane, methane, propanol, ethanol, ammonia, steam, CO, sulfurated hydrogen, smoke, gasoline, spraying fuel, industrial solvent, paint and naphtha.

The WT8823 is powered by 3 x 1.2V nickel-metal hydride rechargeable batteries and is charged from a DC 5V/1A power adapter (an ordinary mobile phone charger); the power adapter is not supplied with the instrument. Batteries must not be charged or disassembled in an explosive environment.
