The Calibration of Air Temperature

The calibration method/procedure of air temperature measuring instruments is showed in the flowchart bellow.

The calibration device mainly consists of standard platinum resistance thermometer (SPRT), Thermometry Bridge, and thermostatic bath. We can calibrate meteorological liquid-in-glass thermometers and temperature sensors.

The Calibration of Air Humidity

The calibration method/procedure of air humidity measuring instruments is showed in the flowchart bellow.

The calibration device mainly consists of precise dew-point meter, standard platinum resistance thermometer (SPRT), standard divided flow humidity generator, and humidity test chamber. We can calibrate mechanical thermo-hygrometers and humidity sensors.

The Calibration of Barometers

The calibration method/procedure of barometers is showed in the flowchart bellow.

The calibration device mainly consists of standard Piston pressure gauge, standard digital pressure gauge, and pressure tank. We can calibrate barometers.

The Calibration of Hyetometers

The calibration method/procedure of hyetometers is showed in the flowchart bellow.

 

The calibration device mainly consists of standard device or rainfall amount and standard device of rainfall intensity. We can calibrate hyetometers.
