The Hanna Instruments HI1333B is a combination (full-cell) pH electrode with a single ceramic junction, polyetherimide (PEI) body, spherical tip, double Ag/AgCl reference, Bayonet Neill-Concelman (BNC) connector, and 1 m (3.3') coaxial cable.
This electrode works with the HI9815 Turtle pH transmitter. A single ceramic junction provides long electrode life in harsh environments. The PEI body with 7.5mm spherical tip is for use in moderately aggressive liquids, such as in wastewater, and for applications requiring stress resistance. The double Ag/AgCl reference provides less noise (unwanted voltages) than gold or silver electrodes. A BNC connector provides tight cable connections.
