Features of hydrogen sulfide sensor
1. Imported first-line brand electrochemical sensors are used, which are stable and durable.
2. Range 0-100ppm, other ranges can also be customized.
3. The measurement accuracy is high, within ±3% FS, and the repeatability can reach within 2%.
4. A variety of analog signal output options: 4~20mA/0~5V/0~10V/RS485
5. Optional high-quality OLED display, the value can be viewed directly on site, and can be displayed clearly at night.
6. On-site power supply adopts 10~30V DC wide-voltage power supply, which can adapt to a variety of on-site DC power supplies.
7. The product adopts a wall-mounted waterproof shell, which is easy to install and has a high degree of protection, which can be used in harsh on-site environments.
