TGS826 NH3 Ammonia Gas Detector Sensor Low Conductivity Resistance To Environment
TGS826 Ammonia Sensor NH3 Low Conductivity Resistance To Environment
*The sensitive element of the sensor is composed of tin dioxide (SnO2) semiconductor, which has very low conductivity in clean air. When the detected gas exists in the air, the higher the concentration of the gas, the higher the conductivity of the sensor.
*Using a simple circuit, the change in conductivity can be converted into a signal output corresponding to the gas concentration.
*TGS826 has high sensitivity to ammonia gas and can detect ammonia gas with a concentration as low as 30ppm in the air. It is an ideal refrigerant critical safety detection sensor, and can also be used for ammonia leakage detection in the agricultural field.
| Applications | Refrigerator gas detection, cold storage ammonia leakage detection, ventilation control in agriculture and aquaculture, etc. |
| Characteristic |

The main parameters:
*Measuring range: 30-300ppm
*Sensitivity (resistance ratio): 0.4-0.7
*Circuit Voltage: 24VDC
*Heater voltage: 5V±0.2V(AC/DC)
