Product Description

Description:

Dry-bulb temperature and wet-bulb temperature sensor, composed of sensor core and shutter housing, can be used outdoors without additional shutter or radiation shield; it has the characteristics of solid structure, long service life, high measurement accuracy, good stability, low power consumption, long transmission distance, strong anti-interference ability, etc., in line with the WMO World Meteorological Organization specification (CIMO Guide). Suitable for all kinds of indoor and outdoor occasions requiring dry-bulb and wet-bulb temperature measurement.

Note: Digital models (RS485 interface models) can be equipped with any combination of integrated sensors for dry-bulb temperature, wet-bulb temperature, air humidity and air pressure, which are easy to install and wire. 

Features:

  • Integrated shutter housing

  • Integrated design

  • Reasonable structural design

  • Good appearance quality

  • Any combination of dry-bulb and wet-bulb temperature, air humidity and air pressure
