Documentation for the GTx116e-PC. The GTx116-PC is an accurate and repeatable thermal dispersion airflow measurement station for ducts and plenums. AFMS features advanced airflow and temperature measurement, alarm capabilities, and the option to connect via BACnet or Modbus. With unparalleled functionality, a ruggedized RH sensor option is available on the GTX116e-PC/H model. The onboard barometric pressure sensor and velocity-weighted temperature accurately calculate relative humidity, enthalpy, and dew point. Both units are ideal for supply, return, and outdoor air intake applications on systems with an airside economizer. Bluetooth® low-energy technology interface is also available.
