Description
Overview
GAOTek Hydrogen Cyanide gas detector is a portable device that can be used to detect a variety of gases, including flammable gases, toxic gases, and oxygen. It is equipped with an LCD dot matrix display that supports Chinese and English operation. The gas concentration unit can be quickly shifted between ppm and mg/m3. The detector also has an ultra-high buzzer alarm sound with settable higher and lower alarm values. Additionally, the detector has a data storage function that allows historical data to be viewed on the device or exported and printed by connecting to a computer.
