The HF5-EX series can only be used together with the intrinsically safe HC2-EX probes to provide a temperature and humidity monitoring system suitable for use in a Zone 1 or 2 Hazardous Area. The relative humidity and temperature can be displayed and output as analogue 4-20mA signals. Calculated psychrometric values such as dew point or mixing ratio can also be derived and provided as one of the output signals. Probes are interchangeable and suitable for mounting in Zone 0/20. Ranges: Temperature -40 to +60C, Relative Humidity 0 to 100%. Accuracy 0.8%RH, 0.1C.
