These provide fast, accurate, and stable pH readings. Ideal for food, pharmaceuticals, or biological samples. Double ceramic junction design protects the inner reference solution and prolongs the life of the electrode. Readings stabilize to 0.01 pH in less than 30 seconds—even with a 50degC temperature change. Electrodes read pH from 0 to 14. Max temperature is 90degC for glass electrodes and 80degC for epoxy. All electrodes have BNC connectors.

Models 05718-20 and 05721-26 have a pin-tip connector, which is identical to the pin-tip portion of a U.S. Standard connector.
