B&C SZ1131 pH Sensor

Combined glass/gel reference pH electrode, 9.5mm diameter Epoxy body and 1.5m cable with BNC connector.

The B&C Electronics SZ1131 pH sensor is a universal digital sensor, compatible with all pH controllers on the market and for all types of stable processes. It provides reliable measurements even at the extremes of the pH range.

This pH electrode allows for precise measurement at an extraordinary cost. Its bulb is constructed of extra-hard glass, while the body is made of epoxy for added protection.

It contains a potassium chloride (KCl) solution inside, which extends its useful life and keeps it in good condition. The sensor does not require additional electrolyte.

Specially designed for greenhouse use.
