Description:
OC-F08 series online gas detector used the original imported sensor and the ultra low power 32 bit microprocessor, so with the advantages of high precision, good repeatability, stable signal, respond quickly, etc. Possible connected with many controller system, such as PLC, DCS, computer and other, with the function of remote monitor and alarm, data logger and analysis.
Common applications is gas safety inspection and alarm for industrial scene for Methane gas inspection.
Features:
Working principle of the TDLAS, will avoid the interference by the dust, temperature and humidity.
No the Zero drift.
Long working life up to 5 years, no need to replace the sensor.
The sensor will not poisoning by the Si, S and others.
Long measuring range could up to 0~100%vol.
High sensitivity up to 1ppm.
With the Ex-proof certificate, the Ex-proof grade is Exd II CT6.
