CTH1000 Mining Carbon Monoxide TesterDetailed product description：

The CTH1000 mining carbon monoxide analyzer is designed and manufactured according to the technical specifications of MT703-97 "Portable Electrochemical Carbon Monoxide Analyzer for Coal Mines" and Q/3200 KQSY 013-2007 enterprise standard. Suitable for continuous monitoring of the percentage content of carbon monoxide in the air in industrial and mining environments.
The CTH1000B measuring device is compact in size and can be used in a pocket. The sensor responds sensitively, and the measuring device uses LCD digital display. If the carbon monoxide content in the air environment reaches the alarm set value, the measuring device will emit an audible and visual alarm signal.
