A standard glass pH electrode with a 12mm body. Electrode requires a separate reference electrode. Most analysis is performed using combination electrodes however the practise of using two separate electrodes does provide a greater likelihood of accuracy. This is due to the pH electrode having a larger glass bulb leading to increased sample contact with a finer glass bulb. The separate reference also has a larger reservoir of filling solution and a larger junction leading to greater stability and longer lifetime.

• Glass body 12mm diameter with sensitive glass bulb
• High degree of accuracy
• Requires seperate referencePH range 0-14
• Temperature range 0-80º C
• Diameter 12mm. Length 120mm(excluding cap)

Supplied with 1 metre cable and BNC connector
