Description
Redox electrode with platinum pin tip in a glass body is a refillable ORP sensor designed for general laboratory work and redox potential titrations. It covers a measuring range of ±2000 mV and uses a single ceramic diaphragm with a flow rate of 15–20 µL/h together with a single Ag/AgCl reference system filled with 3,5 M KCl + AgCl electrolyte. The coaxial cable is 1 m long and terminates in a BNC connector for straightforward instrument connection. Recommended operating temperature spans −5 to 70 °C at a maximum pressure of 0,1 bar; the probe itself contains neither a temperature sensor nor an internal amplifier. Supplied as a single piece from manufacturer Hanna Instruments, this glass redox potential electrode suits routine laboratory redox measurements where a refillable, single-junction design is preferred. Net weight is approximately 0,31 kg. The combination of platinum sensing element, ceramic junction and refillable electrolyte supports stable ORP readings in aqueous laboratory samples under the stated temperature and pressure limits.

Questions about Refillable Combination ORP Electrode with BNC Connector
What is this article?
Refillable Combination ORP Electrode with BNC Connector is the article on this page. Luminix Health distributes Hanna Instruments for laboratory use. It sits in Titrators & electrochemistry systems, inside pH & electrochemistry, in Lab instruments.
A titrator adds a reagent and watches an electrode until an endpoint, then calculates the amount. It is a burette, a stirrer and a meter in one. The electrode and the reagent concentration still decide the result. A manual titration is the same chemistry without the automation.
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.
