Advantages
1. Multiple transmission signals and outputs
The zero correction function and full software automatic calibration function make gas monitoring more accurate and reliable.
Standard 4-20mA, RS485 signal, optional 2 sets of relay signals, 1 set of relay signal output.
Sound and light alarm function, there will be sound and light alarm when reaching the alarm point.
For harsh environments with high humidity, high temperature, and high dust, a pre-treatment system can be selected for cooling, dehumidification, and dust removal to protect the lifespan of the detector.
2. Internal suction pump, fast response
Built in constant flow large suction pump, accurate detection, faster and more sensitive response than diffusion model.
3. Capable of detecting multiple gases and displaying various digital displays
Up to 6 gases can be detected simultaneously. In complex and multi gas environments, multiple installations can be reduced, saving time and effort.
2.4 inch industrial grade high-definition color screen with a resolution of 320 * 240120 degrees wide viewing angle.
Supports ppm and mg/m3 display units. The unit can be switched freely, and the concentration value is automatically converted by the device.
4. Can support wireless transmission (optional)
Optional wireless module (4G&Rolla), data can be uploaded to cloud platforms, environmental protection agencies, or other platforms, providing SMS reminder function, transmission signal is not limited by distance, and can be viewed in real-time on mobile phones or computers.
