Benchtop pH / mV / ORP Meter, Five-Point Calibration
High-resolution benchtop pH and ORP meter reading to 0.001 pH with five-point calibration, selectable buffer sets and a calibration-due reminder, for laboratories working to a defined method.
Typical applications
- Pharmaceutical and fine-chemical quality control
- Research laboratories
- ORP and redox measurement
- Water and effluent analysis
- Method development requiring a defined buffer set

Worth knowing before you order
The ± 0.002 pH accuracy figure is the meter's, not the system's: it is only reachable with a sound electrode, calibrated over the range you actually measure, so the five calibration points and the calibration-due reminder are the useful part of this model rather than the extra decimal place. A general-purpose pH electrode, a temperature probe and buffers 4.01, 7.00 and 10.01 are supplied — but no ORP electrode is listed, and the ORP mode will not work without one, so order a redox electrode alongside if you need it. The 1.68 and 12.45 buffers of the five-point sets are also not supplied.Specification
