Temperature and humidity data logger from -40°C to 125°C. Completely food grade. It is provided with an Accredia (NIST equivalent) traceable certificate.

RHTemp125 XL is a temperature and humidity data logger from -40°C to 125°C (calibration from 25°C to 125°C), managed with Windows software and USB interface (DiskInterface HS, Multibay). Battery is user replaceable and the data logger is provided with an Accredia (NIST equivalent) traceable certificate on different points.

Among the possible applications there are the drying processes monitoring, especially of pasta, of powders and grains storehouses, of extreme environments.

There are also other models of high temperature data loggers, for pressure and temperature only too.




Main features

  • Completely food grade
