The Optidew 401 chilled mirror hygrometer designed and developed by Michell Instruments has proved itself to be a high precision, reliable reference hygrometer for calibrations performed in the Rotronic  UKAS / ISO 17025 accredited laboratory in the UK. Rotronic HG2 models are suitable for the calibration of all manufacturers’ temperature and humidity probes, data loggers and handheld instruments up to the wide ranges -5…60 °C, 2 to 99 %rh.

The digital high-end temperature sensor RMS TCD-S-001 is a new addition to the product range. Its great advantage is that it can be replaced, for example for calibration, almost without downtime and without interrupting measurement.

The advanced high-end HC2A-S3A provides even higher reliability and long-term stability and sets new standards among the non-heated temperature and humidity probes for meteorological applications.

Recently «Azo Sensors» talked to our Director of Environmental Monitoring Systems, James Pickering, about the advantages of using digital sensors in an environmental monitoring system. We are happy to share the Interview.
