high quality RS485 digital nh3 ammonia gas sensor with PVC probe
The ammonia gas sensor is a fixed potential electrolysis sensor. Ammonia gas undergoes a series of redox reactions inside the sensor and releases charge to form a current. The current is proportional to the ammonia gas concentration, and the level of ammonia can be determined by testing the current.

Signal output | RS485/0-5V/0-10V/4-20mA |
Measuring range | 0-100ppm/ custom |
Sensitivity | 0.10±0.03 ppm |
Resolution | 0.5ppm |
Response time | ≤60s |
Operating temperature | -20℃~50℃ |
Operating humidity | 15%RH~90%RH (relative humidity), noncondensable |
