Product Description

The ULT90 Ultra low temperature probeless data logging system is supplied with all that is required to validate appliances and processes operating at -86°C ~ +30°C in compliance with pharmaceutical regulated standards.

Supplied data loggers have integral sensors which are simple to install, rather than wrestling with wires and probe tips that can be disturbed during regular operation, our data loggers are simply placed inside your freezer or dry ice shippers. When partnered with the powerful and easy to use MT4 software, you can rapidly synchronize the data loggers to record and store temperature and time data.  Once your validation exercise has been concluded, graphical, tabular and statistical reports can be generated.

System comprises of;

  • Probe less multiple use data loggers rated to -86°C
  • Calibration certificate
  • Computer interface
  • 21 CFR Part 11 compliant software
  • Carry case
  • IQ/OQ/PQ GMP Validation documentation

Options: Available with 9 or 15 data loggers
