Description
The Rotronic HygroFlex5-EX series consists of two-channel transmitters for the exact measurement of humidity and temperature in explosive atmospheres. This device conforms to the latest international standards. The robust aluminium HF5-EX humidity and temperature transmitters are available with or without display. The attached probes are cast into a stainless steel tube and are certified for operation in explosive atmoshperes.
