The HygroLog NT series is the latest development in data loggers for relative humidity, temperature and dew point.
Thanks to the precision of the new AirChip3000 technology on which they are based, the instruments achieve a
degree of accuracy not seen before .
The new HygroLog NT series not only fulfi ls all FDA and GAMP requirements, but also supports users in validation.
With a storage capacity of more than 47,000 data points, the loggers have a virtually unlimited memory. Measurement
losses are ruled out by the digital communication interface between the HygroClip2 probe and the loggers.
