  • NH3 Monitoring and Detection | Terra Applied Systems

    NH3 Monitoring and Detection. Appropriate and effective sensing is critical to Ammonia/Urea operations for process safety as well as health and safety. Speed and certainty of detection are vital for process control and timely mitigation of accidental release. Immediately dangerous to life or health (IDLH) limits for ammonia are effortlessly monitored using either UV-DOAS (Ultraviolet Differential Optical Adsorption Spectrometer) or TDL (Tunable Diode Laser) technologies.

  • Bump Testing Ammonia (NH3) Sensors

    Exposure to very high concentrations of ammonia can kill the sensor leaving it useless for detection. Therefore, it is important to use a lower concentration of NH 3 gas for bump testing. Depending on what concentration of NH 3 you are using for the bump test, the length of time you will be applying the NH 3 should change.
