Description
Overview
GAOTek portable multi gas detector with the inner pump to detect the gas composite concentration data in different working places. 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 gasses, or 3 gas, or 4 gas, according to different usage. The gas composite will be according to the users’ demands.
