LFH70 Temperature&humidity Transmitter is a highly reliable product developed for high-precision temperature and humidity measurement in fundamental industrial applications and climate control fields. Its split probe can work in environments with temperatures up to 180℃. The high-temperature humidity sensitive capacitor has high long-term stability, strong anti pollution ability, and excellent anti electromagnetic interference ability. Comparing to other HVAC transmitters, the innovative metal structure design gives LFH70 the advantage of stronger structure and and longer duration in harsh working conditions.
Full metal shell, strong and reliable, suitable for harsh working environment.
High temperature range: -40~180℃ .
Temperature&Humidity full range calibration, high accuracy.
Sensitive components endure high temperature, with good humidity repeatability.
The core coating has long-term stability and strong anti pollution ability.
LCD display, buttons, alarm and other modules optional.
