Description
Overview
GAOTek multi gas detector can be used in mobile rapid and accurate detection of a variety of gas concentration and measurement of environmental temperature and humidity, if the measurement exceeded the limit value, the alarm will sound. It adopted advanced electric circuit design, mature kernel algorithm processing, unique external appearance design, had achieved a few patents about the software works, external appearance, and so on. It is possible to simultaneously detect 1 to 5 types of gases, and the units can be switched freely. The types for detection are more than 500 types. This product is unparalleled in its versatility, capability, and overall value. Its adopted water to resistant line of portable gas detectors has transformed the market with its matchless array of features. Continuously monitoring and displaying concentrations of up to 5 gases, the compact and lightweight this was designed and engineered with an extensive host of applications in mind.
