Features

  • pH, ISE, mV, Temperature
  • Digital LogR technology
  • Direct temperature measurement and compensation from the electrode
  • 3-year warranty

The Thermo Scientific Orion PerpHecT benchtop pH meters all feature exclusive digital LogR technology, which allows the pH electrode to read temperature without a separate ATC probe or 3-in-1 electrode. A bright LED display shows an automatically calculated electrode slope. Meters accept a separate ATC probe or manual temperature compensation, if desired. All meters come with a power adapter and feature a 3-year meter warranty.

320, 350 & 370 PerpHecT Benchtop Meters

The 320 PerpHecT benchtop meter performs pH or mV and temperature measurements. The 350 PerHecT benchtop meter has more advanced features including a clock, RS232 data output and a 2.5mm recorder output. Finally, the 370 PerpHecT benchtop adds an ISE (concentration) mode to the features of the 350 PerpHecT.
