Product description
Product Overview
● It adopts a new GUl (graphical user interface) design, a micro vacuum sampling pump, infrared and electrochemical sensors, embeddedmicro-control intelligent control technology, and TFT-LCD display. It candetect the concentrations of four gases, CHa, CO, O2, and HS in the ambi-ent air in real time, and can also display the ambient temperature andhumidity.
● It has functions such as intelligent adjustment, time and voltage display.intermittent sound and light alarm, adjustable alarm point, undervoltagealarm, etc.
● It has WIFl function and Type-C charging interface.
● It can store 5000 sets of data and display historical data curves.
● Can measure at long distances.
