Vaisala Model HMI41 with HMP46 Probe Humidity and Temperature Indicator: Tested and working
▪ RH measurement range 0 ... 100 %RH The Vaisala HUMICAP® Humidity
Indicator HMI41 fitted with the Vaisala HUMICAP® Humidity and Temperature Probe HMP46 can be used for spot checking humidity and temperature in ducts or chambers. Typical applications are plant maintenance, installation and inspection of air conditioning systems, production and storage areas and production processes. In addition, it is suitable for field checking Vaisala's humidity transmitters.
Withstands high temperatures
The HMP46 operates in full humidity range of 0 ... 100 %RH. The temperature range is from-40 to +100 °C (-40 ... +212 °F). For short periods of time, the probe can withstand temperatures up to+180 °C (+356 °F). The HMP46 probe is solid and rugged. Its stainless steel probe is made to withstand rough handling in mechanically demanding applications. The probe’s long shaft can also reach otherwise unreachable places.
Versatile and easy to use
In addition to displaying the humidity and temperature readings, the HMI41 indicator calculates dew point and wet bulb temperature, absolute humidity and mixing ratio.
The indicator has an easy-to-read two line liquid crystal display. The display units (metric or non-metric) are easily selected.
These features, plus fast response time, high measurement accuracy and excellent stability, as well as the wide temperature range of the probe, make the HMI41/HMP46 combination an ideal choice for the most demanding applications.
High performance sensor
The HMP46 probe incorporates Vaisala HUMICAP® Sensor. This sensor has high accuracy, excellent long-term stability and negligible hysteresis. In addition, the sensor is insensitive to dust, particulate dirt and most chemicals.
