Hidden thread, 4-hole screw fixing is more convenient
Good repeatability, low zero drift, fast response time, strong anti-interference
Power supply voltage: DC5-24V, output signal: V- high and low level output, switching value NPN
The shell is made of PC V0 fireproof material, which is safer and more stable
Overview:
The sensor is a fuel cell sensor. Carbon monoxide and oxygen undergo a corresponding oxidation-reduction reaction on the working electrode and the counter electrode and release charges to form a current. The magnitude of the generated current is proportional to the concentration of carbon monoxide and follows Faraday's law. It can be determined by measuring the magnitude of the current determine the concentration of carbon monoxide. With excellent repeatability and stability.
Application range:
Carbon monoxide detection in commercial and civil fields.
Portable carbon monoxide detector.
Fixed point carbon monoxide detector.

Working conditions
chiasma interference:
In addition to the target gas, the CO sensor also responds to other gases. The data in the table are typical responses and carbon monoxide equivalent values of common interfering gases at given concentrations. The sensor also responds to some gases not listed in the table below, and the sensor and equipment should be used according to the actual application scenario.
