The Rotronic HygroFlex5 measuring range is within 0 to 100 %RH and -100 to 200°C (-148 to 392°F), depending on the probe.
The HF5 is designed for fixed installation in HVAC and industrial applications. The HF5 transmitter is compatible with HygroClip2 probes with incorporated AirChip3000 technology. The HC2 (HygroClip2) probe achieves an unparalleled degree of accuracy that has never been seen before. With the combination of advances in sensor technology and integration, the HygroFlex HF52, HF53, HF54, HF55 and HF56 transmitters combined with a HC2-S probe provide superb precision and state-of-the-art functionality.

Ordering Codes
Notes:
• The HF53 can be ordered with both analog and digital interface (see "cable fittings" in the table).
• The enclosure of all models with optional display and keypad and/or with digital interface is designed to beinstalled in the horizontal position.
• The M16 cable grip is located at the bottom of the enclosure. The 1/2" conduit adapter in located on top of the enclosure.
• The factory default setting for the dew point calculation is frost point below freezing.
• The calculated parameter uses the same unit system (metric or English) as the temperature output.
• Custom range: be sure to clearly specify the desired range at the time of order. When a special range has been ordered,the letters ST, SC or S are used in column 4, 7 or 8 in the above table. These generic codes will be replaced with a specificcode only for quantity and repeat orders.
• The probe used with the HF5 must be ordered separately. For technical information on the different probe models, refer todocument E-M-HC2 Probes-V1.
• One (1) AC5005 mounting flange is included with the HF52 and HF53 duct mount transmitter.
