ST8900 4 in 1 Gas Detector Oxygen O2 Hydrogen Sulfide H2S Carbon Monoxide CO Combustible Gas Lel Gas Analysis
ST8900 4 in 1 Gas Detector Oxygen O2 Hydrogen Sulfide H2S Carbon Monoxide CO Combustible Gas Lel Gas Analysis
Description:
This product is a portable handheld instrument that can continuously monitor four different gases: CO, H₂S, O₂, and LEL. When these gases are detected, all concentrations will be displayed on the LCD. The unit also provides user-configurable high and low alarms, as well as STEL/TWA alarm functions. Once the alarm conditions are exceeded, the device has audio and vibrating visual alarms.
Features:
1. It can detect 4 kinds of gases: carbon monoxide (CO), hydrogen sulfide (H2S), oxygen (O2) and combustible gas (LEL).
2. The concentration of CO, H₂S, O₂ and LEL gas in the environment can be continuously monitored, and the measurement is professional and accurate.
3. When the concentration of any one of CO, H₂S, O₂ and LEL reaches the alarm level, the sound and light vibration alarm works.
4. Provide automatic shutdown time and concentration alarm value.
5. Equipped with a large color LCD screen with backlight, which is convenient for reading at night and works normally.
6. It can be connected to a sampling pump to operate in a confined place.
7. It is widely used in shipping, mining, petroleum exploration, chemical industry, gas pipeline, tunnel construction, coal, metallurgy, papermaking, fire protection, municipal administration, textile and other industries.
