Description
InLab® Viscous Pro-ISM is a combined pH electrode built around the SteadyForce™ reference system with DPA electrolyte at 2,5 bar overpressure. That pressurised reference design prevents diaphragm fouling, so the sensor remains contamination-resistant and low-maintenance in viscous and liquid media such as ointments, creams and soiled solutions. A silver-ion barrier and an integrated NTC 30 kOhm temperature sensor complete the SteadyForce™ architecture; connection is via an S7 screw head. Specified working ranges are pH 0 to 14 and 0 to 100 °C, with a membrane resistance of 600 MOhm at 25 °C. Reference electrolyte is Friscolyt-C; the indicated storage solution is Fiscolyt B. Shaft length is 120 mm, with shaft diameters of 12 mm and 6 mm. Net weight is 0,1 kg and the unit is supplied as one piece. This InLab® Viscous Pro-ISM electrode from manufacturer Mettler-Toledo OnLine is intended for laboratory pH work on challenging sample matrices where stable reference performance and integrated temperature compensation are required.

Questions about pH electrode InLab Viscous Pro-ISM
What is this article?
pH electrode InLab Viscous Pro-ISM is the article on this page. Luminix Health distributes Mettler-Toledo OnLine for laboratory use. It sits in pH electrodes & sensors, inside pH & electrochemistry, in Lab instruments.
A pH electrode is a glass membrane and a reference. It is a consumable: the glass ages, the junction clogs, and the reading drifts. A refillable electrode and a gel electrode differ in how they are maintained. The connector has to match the meter. The electrode, not the meter, is usually what is wrong.
A pH meter is a voltmeter on a glass electrode. The voltage tracks hydrogen-ion activity, and the electrode is converted to pH only after it is adjusted with buffers of known value. Conductivity measures how well a solution carries a current, which for dilute salts tracks concentration. Dissolved oxygen and titration are further electrodes on the same idea: a sensor, a standard, and a reading that is only as fresh as the calibration. Buffer values and chemical identity sit on PubChem. Accreditation of the calibration laboratory is the field of BELAC and EURAMET.
