pH and Conductivity Measurements

Overview

Multiple pH meters with standard probes are available, in addition to a pH/conductivity instrument.

Ph Meter Five-Easy-Plus pH meters (FEP20; Mettler Toledo)

Offers easy 3-point with automatic temperature detection and correction and pre-set buffer settings. Fast and accurate measurements are possible with either manual or automatic end-point determination.

Installed with the Lab pH electrode LE438 (Mettler Toledo; range 0-14 pH).

pH meter Five-Go (FG2) pH meters (Mettler Toledo)

Offers easy 2-point calibration with automatic temperature detection and correction and pre-set buffer settings. Fast and accurate measurements are possible with either manual or automatic end-point determination.

Installed with the InLab Ultra-micro pH meter (Mettler Toledo; range 1-11 pH) for solution volumes down to 15 ?L (minimum immersion depth 5 mm)

pH/Cond Seven Excellence The Seven Excellence S470 Meter (Mettler Toledo)

Equipped with pH and conductivity modules, with intelligent sensor management (ISM), to detect sensors automatically and recall saved calibration data. With the easy-to-move U-Place ergonomic probe arm, measure up to 3* parameters simultaneously for increased efficiency with constant temperature.

The large clear colour display and touch screen allows for fast and easy operation of pre-defined or user-defined calibration settings (up to 5-point calibrations), user-defined end-point measurement settings, and user-defined methods.

*Available sensors include and InLab Expert Pro-ISM (range 1-14 pH) for pH measurements, and InLab 731-ISM probe for conductivity measurements (range 0.01 – 1000 mS/cm).

Additional sensors are compatible with the pH/conductivity meters.

Standard calibration solutions are available for pH (4, 7, 10) and conductivity.
