HYGROLOG HL20/21 ADVANTAGES AT A GLANCE.

The new HygroLog HL20/21 series is the latest development of data loggers for relative humidity, temperature, dew point

and frost point. These loggers give you the accuracy and reliability to measure and record your essential data whether it

be in pharmaceutical clean rooms, storage facilities, manufacturing areas, buildings, museums or any other critical area.

The HL20 and HL21 are fully compliant with FDA 21 CFR part 11 and GAMP 4 requirements for electronic records and

electronic signatures (ERES).
