## Description

APERA INSTRUMENTS 201DJ-C Double-Junction Combination pH Electrode is ideal for long time consistent testing in turbid water solutions, such as wastewater, pools and spas, and environmental monitoring. Its double-junction structure prevents the probe from being clogged and contaminated during measurement. Measurement Range: 014 pH, 080?C (32176?F); Housing: Polycarbonate; Junction: Double Ceramic; Reference Electrode: Ag/AgCl; Connector: BNC; Size: ø12 160 mm; Cable: 3 Ft. Not suitable for testing in low-ion concentration solutions (eg: deionized water or distilled water), strong base solutions (pH>12), highly corrosive liquid, or for continuous testing in high temperature solutions (>140?F). Compatible with any pH meters that use BNC connectors. Temperature sensor is not built-in. Users need to have a separate temperature probe to enable ATC or manually input temperature to complete temperature compensation

Review: The best ones I tried as of yet - I use these pH electrodes in a machine that produces chorine solution from splitting salt water with electricity. So the environment is definitely corrosive even for plastics (over time). Electrode has been performing way more stably then a different brand that I used to buy here on desertcart. So I really vouch for these right now, at least for my application. I don't even expect these to last more then a few months since they are constantly dipped in the concentrate, and this one is performing great.
Review: Excellent replacement for Oem - Worked perfectly to replace the comparable unit on my Milwaukee ph tester.
