CTH1000 determination of carbon monoxide, carbon monoxide detection alarm, carbon monoxide detectors 
 The product is a new generation of miniature smart detectors, which can continuously detect the concentration of carbon monoxide in the presence of flammable and explosive flammable gas mixture environment. The instrument uses electrochemical sensor, low-power design, sound and light alarm, background lighting, long life, long working hours. The undervoltage show that the automatic zero tracking, adjustment, easy to use features. 
 The main characteristics and uses: 
 CTH1000 type carbon monoxide detector, imports of long-life electrochemical sensors and micro-power single-chip control bears, four LCD display, the instrument not only has the sound and light alarm, zero tracking, automatic backlight, undervoltage alarm function, but also accurate and reliable long life, small size, light weight, simple operation, easy maintenance, etc.. This instrument is widely used in the continuous detection of the concentration of carbon monoxide gas in the working environment in the presence of flammable and explosive flammable gas mixture. 
 How it works: 
 The working principle of the instrument are: electrochemical sensors directly to the diffusion of carbon monoxide gas reaction environment to generate electrical signals proportional to the measured gas concentrations, into the microcontroller for data processing by the signal conditioning circuit is filtered and amplified, and the LCD screen displayed on the concentration of carbon monoxide gas, carbon monoxide concentration is higher than the alarm set point, the instrument sound and light alarm signals.
