Description
301DJ-C ORP electrode with double diaphragm is ideal for regular ORP measurements in turbid water solutions such as wastewater, swimming pools and spas, as well as for environmental monitoring, and is equally suitable for general aqueous solutions. The double-diaphragm construction minimises the risk that the diaphragm becomes clogged or contaminated during measurement and thereby extends electrode service life, especially during long-term testing in turbid and complex water matrices. Compatible with all ORP meters that feature a BNC connector, the electrode offers a measuring range of ±2000 mV. It employs gel-KCl electrolyte, a platinum needle sensor measuring (Ø0,8×3) mm, an Ag/AgCl reference system and a double ceramic diaphragm. Overall electrode dimensions are (Ø12×120) mm; the outer body is made of polycarbonate (PC). Connection is via BNC with a cable of Ø3 mm × 1 m length. Recommended operating temperature spans 0–80 °C. This ORP electrode from manufacturer APERA Instruments is supplied as a single piece and is backed by a 6-month manufacturer warranty, making it a practical choice for laboratories and field applications requiring robust redox potential sensing in challenging sample types.
This article is part of pH electrodes & sensors, in pH & electrochemistry.

Questions about 301Pt-C Double-Junction ORP Electrode, for turbid solutions, BNC
What is this article?
301Pt-C Double-Junction ORP Electrode, for turbid solutions, BNC is the article on this page. Luminix Health distributes APERA Instruments 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.
