Testo 206 series are perfect for semi-solid and liquid medium. The instruments are unique because of the robust combination pH and temperature probe that measures quickly and precisely in semi solids. Because of the huge gel electrolyte volume and dual wall diaphragm, the probe doesn’t leak, is dirt-insensitive and maintenance free.
