7NH3-500S Ammonia Gas Sensor For Measuring Concentration OfAmmonia Gas

7NH3-500S Ammonia Gas Sensor For Measuring Concentration OfAmmonia Gas

• Product Uses:

The 7NH3 - 500S gas sensor is mainly used for measuring the concentration of ammonia gas. It is designed for specific instruments to ensure personal safety, and can be applied to occasions where ammonia concentration needs to be monitored, such as ammonia - containing industrial production processes, livestock and poultry breeding places with ammonia emissions, and environments using ammonia - based cleaning products.

• Product Features:
  • Wide Measuring Range: With a nominal range of 0 - 500 ppm, it can meet the measurement requirements of ammonia concentration in most common scenarios, and can also withstand a maximum overload of 1,000 ppm.
  • High Sensitivity: The sensitivity at 20℃ is 0.035 ± 0.015 μA/ppm, which can detect trace amounts of ammonia gas, helping to discover ammonia leakage or concentration changes in time.
  • Fast Response: The response time (T90) is ≤ 55 s, which can quickly respond to the change of ammonia concentration, providing timely data support for real - time monitoring.
  • Good Stability: The zero signal at 20℃ is < ± 0.2 μA, and the baseline shift in the temperature range of - 40℃ - 50℃ is < 5 ppm. The long - term output drift is < 2% signal/month, which can maintain relatively stable performance in different environments.
  • Simple Installation: It can be used as a pin - to - pin replacement for standard 7 - series electrochemical ammonia sensors, which is convenient for equipment upgrading and maintenance. And it has no special requirements for installation orientation, with a housing made of ABS material, weighing about 8 g, which is lightweight and easy to install.
  • Intrinsic Safety: It has intrinsic safety characteristics, with a maximum current of < 0.2 mA at 1,000 ppm NH3, a maximum open - circuit voltage of 1.3 V, and a maximum short - circuit current of < 1.0 A, which can be used safely in some dangerous environments.
  • Good Environmental Adaptability: It can work normally in the temperature range of - 40℃ - 50℃, the pressure range of 1 ± 0.1 atm, and the humidity range of 15% - 90%RH (non - condensing), and has a certain adaptability to different environmental conditions.
