Description
Overview
GAOTek portable air quality detector, series portable composite 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 would sound. It adopted advanced electric circuit design, mature kernel algorithm processing, unique external appearance design, and achieved many patents about the software works, external appearance, and so on. It is possible to simultaneously detect 1 to 6 types of gases, and the units can be switched freely.
