Humidity and Temperature Indicator with standard Temperature probe,also includes a calibration option
Humidity Measurement for Professionals
In addition to displaying the humidity and temperature readings, the HMI41 can calculate dewpoint and wet bulb temperature, absolute humidity and mixing ratio — no more awkward conversion tables or complex calculations.

The indicator has an easy-to-read two-line liquid crystal display. The display units (metric or non-metric) are easily selected.

Field Calibrator
The HMI41 indicator also includes a calibration option. The combination of HMI41 indicator and HMP46 humidity and temperature probe is the best choice for calibrating most humidity transmitters in the field at one point quickly and easily.
 
Applications
  • The HMI41 hand-held indicator fitted with the HMP46 probe can be used for spot checking humidity and temperature in applications such as:
  • Plant Maintenance
  • Installation and inspection of air conditioning systems
  • Production and storage areas — freezers, cool stores and containers
  • Production processes in temperatures of up to +180¡ÆC
  • Monitoring the drying of structures after water damages of during construction
