Product Introduction
Adopts high-precision temperature and humidity measurement unit, typical annual temperature drift ≤0.03℃, typical annual humidity drift ≤0.25%RH.
To avoid strong electromagnetic interference at industrial sites, a highly anti-interference analog output circuit is designed.
Both AC and DC power supply are available, DC15~36V or AC24V (±20%).
Flange mounting, using polymer material high-elastic sealing ring to ensure the sealing of the measurement hole.
The highest protection level can reach IP65.
The temperature output range can be modified on site via DIP switches.
The probe rod can be extended up to 2 meters.
