Rotronic HF5-EX TWO-CHANNEL TRANSMITTER

The new HygroFlex5-EX series is the latest development in two-channel transmitters for the exact measurement of humidity and temperature in explosive atmospheres. This device conforms to the latest international

standards. The HF5-EX series consists of a robust aluminium transmitter with or without display. The attached probes are cast into a stainless steel tube, and are certified for operation in Zone 0/20. The transmitter itself is

certified for Zone 1/21.

Features

• Measurement of relative humidity and temperature, optional output of dew point and other calculated parameters

• Safe operation in areas with explosion risk

• Intrinsically safe electrical probe

• Interchangeable stainless steel probes

• Robust aluminium housing
