Rotronic, part of Process Sensing Technologies, has launched a new version of the HygroCal humidity validation instrument. Onsite technical and quality control teams can use the lightweight, portable HygroCal100 Advanced (HC100A) to make quick and simple evaluations of up to seven relative humidity (RH) probes simultaneously.

The HC100A is a fully integrated, standalone instrument, for validating humidity sensors from 5% to 95%RH. This makes it suitable for a wide range of laboratory and process applications, including those in the pharmaceutical, food and semiconductor sectors.

A re-engineered sealed internal test chamber is designed to ensure both stability and uniformity across the chamber are consistent to within ±0.5%RH. With separate saturation and desiccation reservoirs, changing measurement conditions simply requires ambient air to be passed through either reservoir.

Its internal reference, Rotronic’s advanced HC2A-S probe, is designed to provide accurate humidity and temperature measurements within 0.8% RH and 0.1°C, with low annual drift. The probe’s onboard memory means they can be easily exchanged. Additional reference devices choices are available, with users able to choose from handheld humidity instruments to precision chilled mirrors.

An advanced colour touchscreen interface enables quick and simple configuration and operation of the HC100A. Simplifying set-up allows users to define the required calibration procedure. Once set, the calibration procedures will then run automatically.

All measurement and reference data can be stored within the internal memory or downloaded to a PC.

Features include: lightweight, just 3.2 kg; compact, self-contained and fully integrated; fully automatic; simultaneous validation of up to seven RH probes; and quick and simple to use.
