LFH10 Temperature and Humidity Transmitter is specially designed for industrial applications. There are three installation methods:wall-mount, duct type, and split type. Three output models of current, voltage, and Rs485 are optional, with flexiable site installation adaptability. The terminal design is suitable for quick installation. It can be widely used in data room, HVAC, buildings, warehouses and other places need to measure temperature and humidity.
High-precision sensor, long-term stability and anti-interference ability.
A variety of installation methods and output methods are optional.
Compact shell design, LCD backlight display, easy to use.
Power supply and output have overvoltage and reverse connection protection, high protection level IP65.
Multiple temperature ranges optional.
