4NH-500 Electrochemical zero-bias ammonia gas sensor 0-500 ppm
Note: It is recommended to use a PCB socket to connect the sensor, welding can damage the sensor.
Instructions for use:
1. All the above performance specifications are measured at ambient conditions: temperature 20 ℃, relative humidity 50%RH, one atmospheric pressure (100 kPa or ambient pressure).
2. Target gas is recommended for calibration. In the case of calibration with cross-sensitive gases, we do not guarantee the accuracy of calibration and measurement.
3. The cross sensitivity will fluctuate by +/ -30% and may vary with the production batch of the sensor and the life of the sensor.
4. The cross-sensitivity includes but is not limited to the above gases, and the sensor may respond to other gases.
5. T90 index: If the flow rate of a single sensor is 500 ml/min, the T90 index is 90 s.
6. At -20℃, T90 will increase to about 150 s.
| Operating temperature | -20 ℃ to 40 ℃ |
| Operating humidity | 15 to 90%RH (non-condensing) |
| Working pressure | 90 to 110 kPa Bias voltage |
