The screw-in K-Series Reference Cell is an ideal environmentally friendly replacement for the old-style Calomel Reference cells.

The reference cell is used to ascertain the potential of the Silver/Silver Chloride/ Seawater (Ag/AgCl/seawater) half-cell in a BathyCorrometer, UCP1A or UCP1B underwater probe.It has been specifically designed to be used on the BathyCorrometer. This is achieved by removing the stainless steel probe tip and screwing on the K-series reference cell. The potential of the internal Ag/AgCl/seawater reference cell can then be checked.

To be confident in the results, ideally a set of three, different, K series cells should be used. The cells can also be used for checking the UCP1A or UCP1B probes but an adaptor lead (H16) and a high impedance voltmeter (greater than 10 M Ohm) would be required.The electrode is housed in a high resistance PVC body. The reference electrode is supplied with full operating instructions and will give a service life of up to 1 year if correctly maintained and used.
