LFH20 Smart Temperature and Humidity (MTI.AWS.LF.20) transducer is specially designed for indoor temperature and humidity detection. it is small in size, simple in installation and easy to operate. lt has special design for lightning surge, static electricity group pulse, withstand voltage, etc., and has strong anti-interference ability. There are three output modes of current voltage and RS485 to choose from. lt can be widely used in computer rooms, buildings, warehouses and other places where temperature and humidity are to be measured. Our LFH20 Temperature and humidity monitor can be applied in various fields including commercial buildings, industrial facilities, cleanrooms, data centers, healthcare, food and beverage, museums and archives, HVAC systems, greenhouse agriculture, and residential settings.
