Description
Overview
GAOTek Industrial gas detection system is a built-in pump-suction multi gas detector, which can detect 1 to 6 kinds of gases at the same time, continuously monitoring the concentration of various gases online for 24 hrs. Use a 2.4 in (60.96 mm) high-definition color screen to display the on-site concentration in real time, and output 4 mA to 20 mA, RS 485 Standard signal, transmit data remotely. It is with advanced circuit design, mature kernel algorithm processing, obtained several software work patents and appearance patents.
Features
- With internal suction pump, fast response
- Can detect multiple gases, multiple numerical display
- Can support wireless transmission (optional)
- With strong anti-interference, data is reliable
- Powerful function, multiple transmission signals and output
