Relative Humidity & Temperature Transmitters

The new Hygroflex 3 Series is the latest development in HVAC transmitters for relative humidity, temperature and dew point. The HF3 series offers you maximum reproducibility and a guaranteed system accuracy of <2% RH and 0.3 K. The transmitter has 2 or 2x2 wire 4 - 20mA loop outputs or 3 wire 4-20mA/0-10V outputs (User scaleable with software). The transmitters come in various configurations and the optional HW4 Software allows many useful functions to be activated.

The new Hygroflex 5 Series offers the ultimate in performance and flexibility due to its interchangeable hygroclip 2 probes. The HF5 series offers a unique calibration and adjustment process and the ability to interchange probes in just a few seconds. System accuracy is 0.8% RH and 0.1 K. The transmitters come in various configurations and the optional software allows digital versions to be networked together to form a dedicated environmental monitoring system.

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.
