Universal pH probe on the total range : 0 to 14 pH.

The probe is composed of :

· One "glass electrode" formed by a very thin bulb of glass sensitive to pH and welded with the extremity of a crystal tube. The electric resistance of this probe is about 10 000 Mégaohms.
A removable polyethylene strainer protects the pH glass.

· One "reference electrode" (type Ag/AgCl) with plasticized electrolyte saturated with KCL "PLASTOGEL"®. This electrolyte communicate directly with the external medium without interposition of capillary. There is no risk of blocking or draining of the reference.

· A plastic (DELRIN) handle ensures the mechanical resistance of the sensor and the tight sealing of the cable.

· A protection case to maintain the glass electrode in wet atmosphere.
