Wintact WT8822 Hydrogen Sulfide (H2S) Gas Detector

Wintact WT8822 Hydrogen Sulfide (H2S) Gas Detector

The Wintact WT8822 is a novel-looking, compact and portable detector designed for detecting hydrogen sulfide (H2S) concentration. It uses a high-quality electrochemical gas sensor to achieve accurate measurement and stable performance with safety and reliability, over a measurement range of 0~100 PPM (0~0.01 VOL%, 0~152 mg/m³, 0~0.23 LEL%) with a response time of less than 30 s.

The LCD shows the hydrogen sulfide reading together with the temperature of the sensor in °C or °F, the high and low alarm indicators, the buzzer status and the battery level. The reading unit can be switched among %VOL, %LEL, PPM and mg/m³, and the high and low alarm points are set by the user.

The detector meets the stability requirements of industrial site safety monitoring and is widely used in households, the chemical industry, the mining industry, environmental protection, gas transmission and distribution, biochemical medicine and agricultural research. To ensure accuracy, the manufacturer states that the instrument should be calibrated regularly, at intervals not exceeding one year.
