Description

Its not just an ordinary pH meter, it can also measure ORP and ion-concentration in various units. Switching modes before, during or after measurement is easy requiring just a single keypress.

Pressing a single button – READ or CAL – starts a measurement or calibration, with three options for endpointing. With a timed endpoint the analysis endpoints after a pre-defined time interval. It can also be endpointed manually or the instrument can automatically endpoint according to one of three stability criterion: fast, normal or strict.

Features and Benefits

pH calibration support Eight different pre-defined pH buffer groups are available giving you a high degree of flexibility. It is also possible to create your own buffer group. After calibration, the sensor icon shows you at a glance the quality of the calibration.
Ion measurements – flexible sensor choice It is possible to use our perfectION™ Series of combined Ion Selective Electrodes as well as our collection of half-cells. For measurements with half-cell sensors a reference electrode connection is present.
Full ion support The eight most commonly used ion types are pre-programmed to make the settings as convenient as possible. For others, you can enter generic ions with different ionic charges to ensure that the slope is calculated correctly.
Temperature – an important parameter Supports both NTC30kΩ and Pt1000 temperature sensors, with the option of automatic detection or manual selection. Three options for temperature capture exist: an integrated temperature sensor in the electrode, an external temperature sensor or setting the temperature manually.
