This document is the user guide for HygroClip 2 (HC2) Humidity Temperature Probes
The HygroClip 2 (HC2) series consists of digital humidity-temperature probes based on AirChip 3000 technology. These probes feature a UART serial interface and two 0…1 V linear analog output signals. They are designed for use with the HygroClip 2 generation of ROTRONIC humidity-temperature instruments, including hand-held and bench top indicators, data loggers, and transmitters. The HC2 probes also support stand-alone operation using analog outputs or digital interfaces with PC or network adapters.
The manual details various probe models tailored for specific applications, such as climate measurement, tight spaces, spot checks, dust-free granular products, and bulk powders. It provides instructions on hardware and software compatibility, mechanical and electrical installation, operation modes, maintenance procedures like cleaning dust filters, and firmware updates. Technical data sections cover specifications, accuracy, and the effect of cable temperature on probe performance.
