The HM40 is an ideal everyday spot-checking tool for HVAC professionals. The proven Vaisala HUMICAP® 180R sensor provides reliable measurement while the user interface with graphical trend display makes daily operation quick and easy. User interface is available in 10 languages. Remote probe design along with spiral cable makes it easier to measure and check readings in hard to reach places.
In addition to relative humidity and temperature, the HM40 provides five calculated humidity parameters (absolute humidity, dew point, enthalpy, mixing ratio, wet bulb), all available in both metric and non-metric units. The HM40 features an interchangeable HMP113 measurement probe allowing for easy calibration (only the probe needs to be calibrated) or replacement of the probe. Replaces the popular HMI41 Humidity and Temperature Meter.
The package includes:
- HM40 humidity and temperature meter with remote probe
- Calibration certificate (ISO9001 compliant, traceable)
- Light carrying case
- Alkaline batteries 2 x AA sized, 1.5V (LR6)
