Description
Inner electrolyte 20 mL for NH4 electrode is a dedicated filling solution for ammonium-selective electrodes employed in laboratory analysis and online measurement systems. Offered as a 20 mL unit in a one-piece pack, it provides a practical volume for electrode refill and service work where the correct internal electrolyte must be matched to the NH4 electrode. The item has a net weight of 0,028 kg and a gross weight of 0,028 kg, making it a light consumable for electrode maintenance stations and sensor preparation areas. This inner electrolyte from manufacturer Mettler-Toledo OnLine is produced in Switzerland and belongs to the electrode accessory portfolio that accompanies pH electrodes, conductivity sensors, oxygen sensors and related electrochemical tools. Facilities running ammonium ion measurements can keep this 20 mL preparation on hand for routine care of compatible NH4 electrodes. Distinct volume and application labelling support correct selection among related inner electrolytes for different ion-selective electrodes. The product is intended for professional analytical environments that rely on properly maintained electrode systems.
This article is part of pH electrodes & sensors, in pH & electrochemistry.

Questions about Electrolyte for Ammonium ISE, 20mL
What is this article?
Electrolyte for Ammonium ISE, 20mL 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.
