Description
Overview
GAOTek Outdoor 6 Multi Gas Detectoris suitable for multi gas concentration detection in various industrial environments and special environments. With import gas sensor and most advance nanometer semiconductor technology, the product can detect gas concentration rapidly and precisely, and our products are famous of high stability and repeatability. It is fixed installed to detect leakage of flammable gas and toxic gases on industrial sites. It can detect 1 to 6 kinds of gases at the same time. All software automatic calibration, each kind of sensor can calibrate up to 6 target concentration values to ensure the accuracy and linearity of the entire measurement.
