Applicability:

This manual applies to all HC2 probes with firmware version 3.0 or higher. Changes to the last digit of the
version number reflect minor firmware changes that do not affect the manner in which the probe should be
operated.

Overview

The HC2 series are digital humidity-temperature probes based on the AirChip 3000 technology. These probes
feature a UART serial interface and two 0…1 V linear analog output signals.

The HC2 probes are designed for use with the HygroClip 2 generation of ROTRONIC humidity-temperature
instruments: hand-held and bench top indicators, data loggers, transmitters, hygrostats, etc. The HC2 probes
maintain all of the benefits of the original HygroClip technology such as the possibility of hot-swapping probes
and feature significant improvements in the area of measurement accuracy and functionality.

The HC2 probes can also be used as a stand-alone device using either the analog output signals or the probe
digital interface. Connectors, cables and digital interface adapters are available to this purpose. Digital
integration with OEM applications is facilitated by the probe communication protocol options.

The HC2 probes offer the following user functions:

 User

settings

 Calculation of the dew or frost point

 Humidity temperature calibration and adjustment

 Simulator

mode

 Automatic humidity sensor test and drift compensation

 Sensor

 Data

recording

The ability for the user to easily update the AirChip 3000 firmware means that the HC2 probes can be kept up-
to-date regarding any future functionality improvement.

Available in different configurations, the HC2 probe series is designed to meet the requirements of a large
number of applications and environments.

1.1 Hardware and software compatibility

The HC2 probes are compatible only with the AirChip 3000 generation of ROTRONIC humidity-temperature
instruments and are not backward compatible with instruments based on the previous technology.

Configuration of the HC2 probes and access to the probe functions requires a PC with the ROTRONIC HW4
software version 2.1.0 or higher or connection to a compatible instrument from ROTRONIC. For firmware
updates HW4 software version 3.3.0 or higher is needed.
