CTH1000 carbon monoxide detector wholesale and retail, CTH1000 carbon monoxide detector carbon monoxide detector supplier CTH1000 technical parameters, CTH1000 carbon monoxide detector carbon monoxide detector factory direct CTH1000 Products CTH1000 carbon monoxide detector is the use of intelligent determination of carbon monoxide electrochemical element made. Microprocessor processes data, high accuracy, with a voltage indicator, automatic shutdown and other functions, continuous monitoring of ambient air concentration of carbon monoxide, and overrun sound and light alarm; display continuous working time of up to 150h or more, charging charging the battery voltage, when the overpressure can automatically stop charging. The assay uses a high-brightness LED LED digital tube, very eye-catching visual readings, small size, light weight, stable and reliable, simple operation and maintenance, is widely used in the coal mine for all occasions detect carbon monoxide concentrations. CTH1000 carbon monoxide detector Model significance zmjt11 Model: CTH1000 carbon monoxide detector C-- detector (measuring) T-- electrochemical carbon monoxide H-- 1000-- main parameters: Measuring range (0 ~ 1000) × 10-6CO CTH1000 carbon monoxide detector working conditions Operating temperature: 0 ~ 40 ℃; ambient relative humidity ≤98% (temperature at 25 ℃); Atmospheric pressure: 86kPa ~ 110kPa; mine have gas or coal dust explosion hazard in. Storage temperature: -40 ℃ ~ + 60 ℃. CTH1000 carbon monoxide detector structure and working principle CTH1000 carbon monoxide detector sensors by section, operational amplifiers, microprocessors, LED displays, alarm circuit, charging circuit, charge control, voltage regulator circuit. Carbon monoxide sensor detects a signal to the microprocessor via the operational amplifier to the monitor after treatment, indicating the corresponding concentration of carbon monoxide, when the concentration reaches or exceeds the set point alarm, the alarm circuit, audible alarm, battery voltage When reduced to 3.75V, undervoltage point on the (last decimal point), when the voltage drops below 3.7V, measured automatically shut down.
