The testo 206 series is ideal for pH measurements in liquid and semi-solid media. The instruments offer a combination of a pH immersion probe and a temperature probe for precise and fast temperature compensation. Thanks to the large volume of gel electrolyte and the dual wall diaphragm, the probe is leak-proof, maintenance-free and insensitive to dirt.
