testo 205, 206, 230 Compact pH Measuring Instruments With innovative probe engineering pH CThe new pH measuring instruments with innovative probe engineering Measurement of the pH value plays an With the development of different, breakproof important role in many areas. Anywhere where probe geometries, Testo is making available there are chemical and biochemical reactions, special solutions for liquid as well as for the pH value has an important indicator semi-solid substances. function. The leakproof storage solution is also new. Although the technology to accurately measure pH probes must be stored in moist conditions pH value has been available for several years, when not in use, in order to prevent the glass instruments previously available have posed membrane coating around the measurement several problems for users: electrode and the diaphragm from drying out. pH1 probe head for liquids Pure water alone should not be used since Short life span of pH probes due to glass water would release the conducting breakage and dirt ingress, for example components contained in the probe Sensitivity to dirt of the pH probe resulting in electrolytes. A potassium chloride solution is incorrect measurements usually used for this purpose. As with every Spillage of storage solution liquid, it can leak which, particularly in the food Handling problems when calibrating branch, can lead to contamination of raw Lack of one-hand penetration pH probes for foodstuffs or products. liquid and semi-solid substances Testo has produced a solution that has Lack of combined temperature and pH eliminated this disadvantage. The potassium measurement chloride solution is available in a gel filled cartridge that does not drip or leak. Together with experts from trade and pH2 probe head for semi-solid substances industry, Testo has developed innovative instruments that resolve these problems. Instead of a liquid electrolyte, Testo pH probes have a gel electrolyte as a reference substance for pH measurement which facilitates the use of a hole diaphragm between the measurement electrode and housing in place of the micro- porous structure usually used in pH probes. The micro-porous structure becomes blocked up more quickly, similar to a finely woven sieve, consequently requiring regular service which in return results in a shorter life. Interchangeable probe Due to the large volume of gel electrolyte and the hole diaphragm, Testo pH probes are not only leakproof, they are almost completely maintenance-free, robust and unaffected by dirt and dust. The combination of the pH penetration tip and temperature probe in a one-hand instrument for accurate and fast temperature compensation is unique. Consequently, accurate readings are guaranteed in all ambient conditions. The potassium chloride solution bonded in the gel cannot leak 2
