This Temperature and Humidity sensor offers ± 1.8% RH (at 25°C) and ± 0,2°C temp accuracy, which makes it ideal for professional meteorology use, as well as environmental and industrial measurements. The use of digital SDI-12 interface protocol makes the sensor easily compatible with wide range of data loggers.
The housing of the sensor is made of POM – C, highly rigid material known for its hardness, durability, good creep resistance and low water absorption. As the material is fully ESD resistant, the sensor can be installed in Electrostatic Discharge Protected Areas (EPA).
- Measurement ranges: 0 – 100% RH; -40 ... +60°C
- SDI-12 output
- POM-C enclosure, extremely robust
- Fully calibrated with 1,8% RH accuracy
- Low power consumption
- Excellent long-term stability
