Product Description

The Duct Type Humidity Temperature Transmitter measures temperature and relative humidity in air ducts. The probe filter at the bottom of the duct temperature and humidity sensor is made of 25um high-strength stainless steel material, which can not only ensure the entry of gas molecules but also prevent the entry of dust particles and water droplets. The pipeline installation method is convenient for on-site installation. It adopts anti-interference circuit design and can withstand various strong electromagnetic inter preferences such as on-site inverse. Besides, the equipment adopts waterproof casing design.
