Ph, ORP, ISE, EC, TDS, Resistivity, Salinity

  • The Hanna pH/ISE and Conductivity Bench Meter - HI 4522 is a research grade, benchtop instrument that features 8 measurement ranges: pH, ORP (Oxidation Reduction Potential), ISE, conductivity, resistivity, TDS, salinity and temperature. It incorporates dual channels (pH/ORP/ISE and EC/TDS/Resistivity/Salinity) with a separate temperature input and supports the external reference electrodes required by half cell pH and ISE sensors.

    The user interface is customizable and capable of displaying two channels at the same time, showing the measurements in various modes: basic measurement with or without GLP information, graph or logging data. Clear tutorial messages and directions are available on-screen to quickly and easily guide users through all measurement and calibration procedures to ensure measurements and calibrations are performed properly. Automatic, semiautomatic and manual pH calibration is available in up to five points, with eight standard and up to five custom buffers. Three selectable logging modes are available: Automatic, Manual and AutoHold logging. Up to 100 logging lots with up to 10,000 recods each can be stored for automatic or manual modes along with up to 200 USP reports, and up to 100 ISE methods reports.

  • Hanna's pH/ISE and Conductivity Bench Meter is like the Da Vinci of lab benchtop meters. Name any parameter and there's little chance it can't measure it. Just this one gear can make any simple room a laboratory. The reliability and accuracy of the instruments comes from Hanna's decades of experience in working similar areas. Also of note is its large memory that is capable of storing lifetime of results of any small laboratory.
