pH & Ion Electrodes

Needle pH Electrode

A combination pH electrode in a 20g needle (0.9 mm dia). The stainless steel tube provides protection for the internal miniature glass pH sensor. It does not require an external reference electrode. The reference solution can be replaced. The electrode is stored wet. Tip length is 1.8 mm, response time ~10s, pH range 1-14.

18g Tube pH Electrode

A combination pH electrode in an 18g stainless steel tube (1.25 mm dia). The stube provides protection for the internal miniature glass pH sensor. It does not require an external reference electrode. The reference solution can be replaced. The electrode is stored wet. Tip length is 1.5 mm, response time ~10s, pH range 1-14.

11g Tube pH Electrode

A combination pH electrode in an 11g stainless steel tube (3 mm dia). The stube provides protection for the internal miniature glass pH sensor. It does not require an external reference electrode. The reference solution can be replaced. The electrode is stored wet. Response time ~10s, pH range 1-14.

Combination Gastroesophageal pH Electrode

This miniature combination pH/reference electrode has a long (1 m) flexible tube to fit into the oesophagus. It does not require an external reference electrode. The reference solution can be replaced. The electrode is stored wet. The tube OD is 1.6 mm, response time ~10s, pH range 1-14.
