The ATEX / IECex Rotronic humidity and temperature probes can only be used with our HF5-EX ATEX / IECex transmitter in applications with explosive atmospheres. The probes measure temperature from -40…85°C and humidity from 0…100 % rH with an outstanding accuracy of ±0.8 % rH / ± 0.1 K. The probes are cast into a stainless-steel tube and are certified for operation in explosive atmosphere (Zone 0).
