A versatile and easy-to-use instrument to fulfil the stringent demands of Good
Laboratory Practice.
- Printout and storage of results to comply with GLP for full traceability
- More confidence in results thanks to calibration reminder when a new calibration
is required
- Storage of last 9 calibrations helps you keep track of electrode condition
- Alarms in pH, mV and temperature
