pH is widely used to express the acidity or alkalinity of a wide variety of products. As an essential product property in many industries, pH is very frequently measured for a number of reasons. Product quality, stability, acidic strength or effectiveness of products/solutions, and applicability in product specific areas are just a few of those.

This is no different in water based paints, coatings and inks. Here the pH is an important parameter not only during production, but also for the final products. Among them are emulsion stability, wetting behavior, matching the products properties with those of the objects to which these will be applied and preventing colors to fade away.

Sentron's advanced microchip sensor technology allows the design of rugged, glass free (virtually unbreakable) probes, that utilize a solid state ISFET (Ion Selective Field Effect Transistor) pH sensor, for fast, accurate measurements, requiring minimal maintenance.

The Standard probe is best suited for general testing and most common applications.  The cut-out tip design also allows testing of small sample volumes by simply placing a single drop on the sensor surface.  The standard probe is an effective means for testing expensive or limited volume samples.

The ConeFET probe is ideal for measuring pH in thick or sticky samples.  Because of its shape, it is also easily cleaned, making it very suitable for pH testing in strongly contaminating applications

The LanceFET's stainless steel tip allows easy penetration in dense, very viscous samples and even semi-solids.  The conical shape offers the same cleanability as the ConeFET, yet with far greater penetrating capabilities. This probe is especially useful for testing whole muscle meats and cheeses.

The SENTRON MICRO electrode is made of PEEK and has a diameter of only 3 mm. The measuring part (the sensor) is built-in at the conic end of the electrode. Therefore this electrode can be used for measuring of very small volumes or in very small sized sample cups and in micro-titer plates.

 

These electrodes can be used in applications in thin high pipes or to measure the pH in meat (stainless steel) and cheese. The MICRO electrode can be connected to one of the 4 SENTRON pH meters and are very suitable for applications in the bio-technology, food, pharmacy, etc.
