Practical solution for pH calibration

March 2006 Maintenance, Test & Measurement, Calibration

Most calibration solutions are kept in large bottles. Since the pH probe cannot be placed inside the bottle, due to contamination issues, another container is needed for calibration purposes. This procedure is often not practical as it can become messy and also wastes solution.

Testo has introduced a new pH range that comes with a unique calibration bottle that is specifically designed for calibration purposes. It is equipped with a dosing chamber that has millimetre measurements, which enables the user to use the correct amount of solution - every time, reducing wastage. Testo's pH meter fits straight onto the top of the dosing chamber, thus, assuring easy calibration of the pH probe.

The new pH range is suitable for semi-solid and liquid materials and is easy to use due to its two-line display, one touch button for automatic recognition of the end value and cable-less portability. Each pH meter comes with both a temperature probe and pH probe ensuring accurate readings in various temperature conditions.

Testo's new potassium chloride storage solution is a gel and not a liquid. It cannot leak and the probes will not dry out - and will last longer. The storage gel comes in a preservation cap, which clicks onto the probe after use.
