The HI 1131B is a pH electrode with a Bayonet Neill-Concelma (BNC) connector.
The electrode is made from glass, has a 3 mm spherical tip, and is filled with a KCl 3.5M and AgCl electrolyte. The junction is made from ceramic, and it is a single reference Ag/AgCl electrode.
The electrode has a range of 0 to 13 pH, 0 to 100 degrees C (32 to 212 degrees F) and maximum pressure is 0.1 bar. It comes with a coaxial 1 m (3.3’) cable and is recommended for usage with samples less than 100 uL. Flow rate is 15-20 uL/H and dimensions are 120 mm (length) by 9.5 mm (spherical tip diameter) by 12 mm (end width).
pH electrodes are used for measuring the pH of a substance. They are often constructed of glass, which senses hydrogen ions, and generates a millivoltage that is picked up by the filling solution and transferred to a wire that connects to the pH meter.
Hanna Instruments manufactures a wide variety of analytical instrumentation, including pH meters, multi-parameter meters, electrodes, chemical reagents, and buffer solutions. Founded in 1978, Hanna is headquartered in Woonsocket, RI, with subsidiaries in 32 countries. Hanna Instruments holds many firsts in the field of analytical instrumentation, including a pH electrode with a built-in temperature sensor, an electronic pocket-sized pH tester, and a replaceable electrode pH pocket tester. To ensure the quality of its products, Hanna is a vertically integrated manufacturer and does not subcontract any part of its manufacturing.
