2. Product overview
2.1 Introduction to HMP60 and HMP110 series
Vaisala Humidity and Temperature Probes HMP60 and HMP110 Series are simple and cost-
effective humidity transmitters suitable for various volume applications:
• Integration into other manufacturers' equipment
• Incubators
• Glove boxes
• Greenhouses
• Fermentation chambers
• Data loggers
• Handheld meters
HMP60 series probes use the interchangeable Vaisala INTERCAP
â
sensor. No recalibration is
required after sensor replacement.
HMP110 series probes use the Vaisala HUMICAP
â
180R sensor for increased accuracy. For
applications where H

O
2
(for example, vaporized hydrogen peroxide (VHP)) is present,
HMP110 series probes can also be ordered with the HUMICAP
â
180V catalytic sensor. HMP110
series probes require calibration after sensor replacement. This can be done with Vaisala
Insight PC software or on the serial line using the optional Vaisala USB cable.
