Functions

HP23

Delta Probe or User defined

parameter

o %RH, temperature and calculated parameter difference (probe 1

less probe 2). This is available only when the calculation of a

user defined parameter is not enabled.

o Using the HW4 software, the HP23 can be set to calculate up to

two user defined parameters

Data capture

o Manual data capture of %RH and temperature + date and time

stamp (HygroClip 2 probe only)

o 8 separate data bins (each can be given a specific name with

the HW4 software)

o Up to 250 records per data bin

Data logging

o Configurable log interval (from 5 sec to 1 hour)

o Start-Stop or Loop mode

o Up to 10,000 RH+T records for a single HygroClip 2 probe

o Up to 10,000 records for a single 1-channel analog probe

o Each data record is given a date and time stamp

o Recording capacity per probe is cut in half when two probes are

being simultaneously recorded

Calibrator

o Can be used to calibrate and adjust HygroClip probes,

transmitters and other devices based on the AirChip 3000

technology

o Fully fledged calibration and adjustment function

o Calibration against reference probe or reference environment

Water activity measurement

o Conventional water activity measurement

o Accelerated water activity measurement

o Automatic end of measurement

Simultaneous measurement of two probes (HygroClip 2 only)

Service connector
