Long Reach Combination pH Electrode


Long Reach pH Combination Electrode with BNC Connector.

SKU: E8086 Category:

A glass bodied long reach pH combination electrode with a 6mm diameter tip for the lower 15cm section.

  • Fast response
  • High Quality. Made in the UK
  • Compatible with all common pH meters
  • Ideal for small samples
  • Perfect for samples in tubes or vials

The EDT E8086 is ideal for the measurement of small samples in small containers or tubes or for inaccessible samples which are deeper inside vessels or reaction chambers etc. The upper part of the electrode is a standard 12mm diameter and fits all standard cell holders and clamps.

The E8086 does not require a separate reference electrode and is compatible with all EDT pH meters and most modern alternatives with a BNC socket.

Many long reach pH electrodes have tips which are 3.5 or 3.7mm diameter making them very fragile and impractical for use in a busy laboratory. The EDT E8086 has a toughened glass tip and a ceramic reference junction which ensures excellent stability a fast response time. The electrode is refillable with KCL filling solution saturated with Ag/AgCl.

The E8086 pH combination electrode comes complete with a 1 metre fixed cable and a BNC connector. For some standard applications it may be best to use the E8080 rugged polymer pH combination electrode or the E8081 standard Glass electrode unless the samples are too small to accommodate those electrodes.

Not suitable for TRIS Buffers. Calibration is normally performed using two pH buffer solutions and a temperature probe for Automatic temperature compensation (ATC).
