ND-RHC High-Precision Air Temperature & Humidity Sensor
What is the ND-RHC? The ND-RHC is a high-precision lab-grade air temperature and relative humidity sensor with optional ISO 17025 (SCS/UKAS) or NIST calibration certificates. Delivering ±0.1 °C and ±0.5–0.8 % RH accuracy from a standard radiation shield, it is the reference choice for pharmaceutical and food industry compliance, building services equipment, paper and textile manufacturing, smart agriculture, urban heat islands, greenhouses and frost alarming connected to the yDoc ML-525 datalogger.

Integration
Powered by the yDoc ML-525 datalogger
The ND-RHC connects directly to the yDoc ML-525 datalogger. The yDoc powers the sensor, schedules measurements, stores readings locally and transmits them to the Sensor-Online platform via 4G/LTE-M, NB-IoT, LoRaWAN, satellite or Ethernet — with up to 10 years of battery life.
