- Temperature & Humidity Meter
- Temperature & Humidity Transmitter
DESCRIPTION
LFH52 Temperature & Humidity Transmiter is specially designed for outdoor temperature and humidity detection.
The Radiation Cover can protect from wind and rain, and provide the best protection for the transmitter in severe weather.
There are 3 output modes of current, voltage and RS485 available. Can be used in construction sites, weather monitoring and other outdoor occasions.
FEATURES
- Standard 5-layer radiation cover, protection from sunlight radiation and rain, good stability.
- The number of layers of the protective cover adjustable, so height is adjustable, convenient installation.
- The output has reverse connection protection function, high protection level up to IP65.
- Long service life and strong anti-interference ability.
