A pH meter electronically measures the acidity or alkalinity of liquids by means of a probe. When the device is not being used, the probe (electrode) should be kept immersed in a suitable liquid (preferably a 4.0 buffer solution) to avoid dehydration causing inaccuracies. Equipment that is used for measuring pH should be regularly calibrated to ensure accuracy.
pH meters come in a wide range of types, costs and accuracies from simple and inexpensive pen types to expensive and intricate laboratory models.
PH METER APPLICATIONS
Different types of pH meters are used throughout industry and in laboratories worldwide.
They also have uses around the home – for example to check swimming pools, fish aquariums and soil alkalinity etc. Pharmaceutical, wine making and food manufacturing laboratories rely heavily on the accuracy of pH meters to monitor processes and product quality and although most types of pH meters are robust, users need to ensure that they remain in good working order and accurate.
PH METER CALIBRATION PROCEDURE
Equipment used to measure pH is first thoroughly cleaned and then checked to ensure that it is not damaged. CMS uses calibrated state-of-the-art master equipment to verify that customers’ equipment is measuring pH within an appropriate range of accuracy and if not, is adjusted (where possible).
pH Meters are returned to clients with a comprehensive calibration report within three working days of receipt.
