OC-1000 Portable multi gas detector for NH3 and CO2

gas detector


OC-1000 portable multi gas detector with the inner pump to detect the gas composite concentration data in different working place. Our engineer design it with 6 sensors at most: one is default of the Temperature & Humidity sensor, so when workers need to inspect the gas concentration, it can detect 5 gas type at most, users can choose 2 gas, or 3 gas, or 4 gas, according to different usage. The gas composite will be according to the users demands.


Semiconductor technology of ultra low power 32 bit microprocessor, 24 bit ADC acquisition chip, so with the high accuracy.

3.5 inch IPS industrial grade color screen.

Support Chinese or English operation menu.

Gas concentration unit available for PPM, %VOL, mg/m3.

For 1~5 gas detecting, gas type all be customized, supporting the PM2.5 particle counter sensor, and humidity sensor, etc.

Internal sampling pump for suction, the suction strength is adjustable in different level.

Explosion proof grade is Exia ⅡCT4.
