Product Description

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).

Innovation In Humidity And Temperature Measurement

  • Highest accuracy at 0.8 %rh and 0.2 oC
  • Outstanding long term stability
  • 20000 data point memory with date & time stamps
  • Programmable alarm limits
  • Programmable recording intervals
  • Psychrometric calculations of dew and frost point values available
  • FDA 21 CFR Part 11 / GAMP 4 compliant
  • USB interface
  • Long battery life

AirChip3000 :

  • Temperature compensates humidity with over 30000 reference points
  • Dew/frost point calculation
  • Sensor auto-diagnostics and automatic correction
  • Active alarming and information
  • Conforms to FDA21 CFR Part 11 and GAMP4 (audit trail)

Optional display :

  • Display of data on a clear, backlit graphic display
  • Battery charge indicator
  • Display of measured and calculated data
  • Function key to start and stop logging
  • Display resolution to 2 decimal places

Data logging function :

  • HL20: Logs up to 20000 value pairs, relative humidity and temperature
  • HL21: Logs up to 20000 data values, temperature
  • Each record is date and time stamped (real-time clock)
  • Adjustable log interval
  • Two data recording modes: (start-stop or loop)

Alarm function :

Visible alarm can be programmed for the HL20 or HL21 detects the following:
  • Out-of-limits value (dened with HW4 software)
  • Communication loss with the probe
  • Sensor failure and sensor drift

Applications :

Long term recording of humidity and temperature measurements is essential in many production, storage, transportation, display and test applications as well as in buildings and museums. They provide valuable information on the levels and variation of humidity and temperature which can have a signicant impact on people, materials and objects.
