CLH100 Hydrogen sulfide analyzerDetailed product description：

The CLH100 hydrogen sulfide analyzer is a new generation of miniature intelligent detector that can continuously detect the concentration of hydrogen sulfide in environments containing flammable, explosive, and combustible gas mixtures. It has the characteristics of sound and light alarm, clock and voltage display, undervoltage alarm, zero point automatic tracking, calibration, and easy use.

Product Usage
The CLH100 hydrogen sulfide analyzer (hereinafter referred to as the instrument) adopts an electrochemical sensor, an embedded microcontroller for intelligent control, and a four digit LED display. Small in size, light in weight, easy to operate, and convenient to maintain, the instrument adopts a thin film touch switch with good sealing performance and accurate *. The CLH100 hydrogen sulfide analyzer is widely used for continuous monitoring of hydrogen sulfide concentration in working environments such as coal mines, metallurgy and chemical engineering, and environmental protection sites where flammable, explosive, and combustible gas mixtures exist. It also provides sound and light alarms when exceeding the limit.

Working Principle:
When the CLH100 hydrogen sulfide analyzer is used to measure hydrogen sulfide in the air, the electrochemical sensor reacts directly with the gas in the environment through diffusion, producing a linearly changing voltage signal. The signal is amplified by a linear amplifier and input into the A/D converter in the microcontroller to be converted into a digital signal. After data processing by the microprocessor, the concentration of hydrogen sulfide is displayed on the digital tube. When the concentration of hydrogen sulfide exceeds the set alarm point, the instrument emits an audible and visual alarm signal. The CLH100 hydrogen sulfide analyzer has battery undervoltage alarm and automatic shutdown functions.
