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°C
Monitoring
the drying of structures after water damages of during
construction
