pH & Water Analysis - pH & Temperature Meters Testo 200 Series

Instead of a liquid electrolyte, these probes use a gel as a reference substance for pH measurement. This 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.They are almost completely maintenance-free, robust and unaffected by dirt and dust.,Gelcap,A potassium chloride solution is usually used to store pH probes which, as with every liquid, can leak. To prevent this the potassium chloride solution is available in a gel filled probe/meter cap that does not drip or leak.
