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. |
