GLASS PH ELECTRODE WITH RED BANANA PLUG
Quick Overview
The Glass pH Electrode with Red Banana Plug by Apex Labs is a high-accuracy chemical-resistant sensor designed for lab-grade pH testing (0.00–14.00 pH). Equipped with a standard 4mm red banana plug, it seamlessly connects to traditional analog meters, educational equipment, and benchtop potentiometers.

The Glass pH Electrode with Red Banana Plug manufactured by Apex Labs is engineered for high-accuracy electrochemical measurements across educational research, chemical manufacturing, and analytical testing laboratories.
Constructed with a premium borosilicate chemical-resistant glass body, this sensor delivers exceptional zero-drift stability and rapid response times. It performs reliably when testing aggressive chemical solutions, organic solvents, and strong acid-base concentrations where plastic body sensors may fail.
Featuring a standard 4mm red banana plug pin connection, this electrode guarantees low-resistance signal transfer to legacy laboratory potentiometers, custom scientific instrumentation, and dedicated benchtop pH indicators.

Frequently Asked Questions (FAQ)
Q: Will this electrode work with standard BNC pH meters?
A: This specific model features a standard red banana plug. If your pH meter uses a BNC port, Apex Labs also manufactures BNC-terminated glass and plastic pH electrodes. BNC-to-banana adapters can also be provided upon request.
Q: How should this glass pH probe be stored when not in use?
A: Store the glass bulb in the included protective cap filled with 3M KCl electrolyte solution. Never store the electrode in distilled or deionized water, as it degrades the reference junction.
