Benchtop pH Meter - pH/ORP Laboratory Meter - -2.00 to 20.00 pH - ±0.01 pH Accuracy

The Master Science Benchtop pH Meter measures pH, ORP (mV) and temperature in laboratory samples with ±0.01 pH accuracy. Automatic buffer recognition, one to three point calibration and automatic temperature compensation keep routine measurements quick and consistent.

A 7-inch white-backlit display shows readings, stability status and calibration information clearly, while results can be stored on the meter and exported to a flash drive or optional wireless printer.

Common Laboratory Problems and How This pH Meter Helps

How the Master Science Benchtop pH Meter helps with typical pH testing issues:

• Readings taken before the electrode stabilises: the stable indicator shows when to record.
• Temperature errors: ATC compensates automatically.
• Lost handwritten results: data is stored and exported digitally.
• Splashes on the meter: IP54 protection guards the housing.
• Awkward electrode handling: the flexible holder keeps the probe in place.
