Description

pH-meter for Industry - OpH228

Expert and professional pH-meter for Industry

  • Inherited from Radiometer PHM220 (same designer)
  • Compatible with existing Radiometer pH meter fleets
  • Easy connections
  • Reliable and fast results
  • Data transfer (Regressi, Excel and ExAo)
  • Easy-to-use interface
  • Durable with a 5-year warranty (excluding consumables)
  • Measurement history (quality control - customizable measurements)
  • GLP menu for measurement traceability

Calibration

The pH meter calibration menu allows calibration on 1-4 buffers (automatic, free by adjustment, or manual) from two sets of buffers (IUPAC or 4-7-10). A free mode allows manual buffer value adjustment. Calibration parameters from the last manipulation can be reused.

Data Transfer

Calibration parameters are stored and can be exported to a .txt file via USB. Compatible with almost all Ex.A.O. systems (Regressi included):

  • USB to Excel
  • By RS232 to acquisition cards
  • By analog output to acquisition cards

Measurement Modes

Two modes are available: manual mode (continuous pH reading with stability indicator) or automatic mode (result freezes at 100% stability).

Connecting the Electrodes

Single or combined electrode via BNC plug. Reference electrode via 4 mm banana plug. Temperature probe via CINCH input. Manual temperature entry also possible.
