Thermohygrographs/Temperature and Humidity Recorders
Thermohygrographs/temperature and humidity recorders can usually record continuously the temperature and humidity readings on a chart. For a thermohygrograph, the sensor and the recording mechanism are usually housed in the same cabinet. Other designs of temperature and humidity recorder usually employ the combination of an electronic temperature/humidity sensor/meter and an electrical chart recorder.
The thermohygrographs/temperature and humidity recorders will be calibrated by comparing against the Laboratory standards in the calibration chamber of a humidity generator.
