This is a HygroMet4 device instruction manual, which introduces the features and installation methods.
This document serves as a short instruction manual for the ROTRONIC HygroMet4 series of meteorological probes. It describes the main functions, including the use of heated sensors for relative humidity and temperature measurement, and provides guidelines for mechanical installation to ensure optimum performance. The manual emphasizes selecting a representative installation site and ensuring sufficient air movement.
| Humidity Range | 0...100 %RH |
|---|---|
| Temperature Range | -40...85 °C |
| Accuracy (Humidity, heated) | 1.5 %RH |
| Accuracy (Temperature) | 0.1 °C |
| Supply Voltage | 15...24 VDC |
| Protection Rating | IP65 |
For maximum accuracy, calibration is recommended about every six to twelve months.
An air velocity of at least 1 meter per second is required to facilitate adaptation to changing temperatures.
Yes, the calibration can be performed by the user himself on site or in the laboratory/workshop.
