HI 4222  pH, mV, and Ammonia Meter Kit   HI 4222  pH, mV, and Ammonia Meter Kit

HI 4222 is a research grade pH, ORP and temperature benchtop meter. This instrument incorporates dual channels with a separate temperature input and support the external reference electrodes required by some pH and ISE sensors.

The customizable user interface can display two channels at the same time, showing the measurements in various modes: basic measurement with or without GLP information, graph or log history.

These instruments offer multi-language support and contextual help is available through a dedicated Help key. 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 procedures are performed properly.

HANNA’s pH Calibration Check™ diagnostics system ensures accurate readings every time by alerting users of potential problems during the calibration process. The Calibration Check™ system eliminates erroneous readings due to dirty or faulty pH electrodes or contaminated pH buffer solutions. After the guided calibration process, an electrode condition indicator is displayed on the LCD informing the user of the overall pH electrode status.

Automatic, semiautomatic and manual pH calibration is available in up to five points, with eight standard (1.68, 3.00, 4.01, 6.86, 7.01, 9.18, 10.01 and 12.45) and up to 5 custom buffers. The Out of Calibration Range and Cal Due features alert the user in the event the measurement is far from the calibration point or when the meter is due for recalibration. Proper, scheduled calibrations are crucial for accurate and repeatable measurements.

This instrument also features up to five point Manual Selection and Custom Standard ISE calibration. From the on-screen list, users can select their ISE electrode parameter along with it’s standard configuration profile or create their own.

Up to a four point automatic or custom standard conductivity calibration can be performed in up to four points as well as probe cell constant

Up to 10 profiles can be saved and recalled, eliminating the need to reconfigure each time when a different electrode is used. User definable configurations can include: temperature compensation in accordance with each parameter, ISO-potential points for pH and ISE, measurement units of ISE concentrations and ISE electrode type, temperature units. Three selectable logging modes are available: Automatic, Manual and AutoHold logging. Up to 100 logging lots can be stored for automatic or manual modes along with up to 200 USP reports, and up to 100 ISE methods reports. Automatic logging features a selectable area and sampling period while GLP information includes complete data about user calibration of each parameter and identification information for the instrument, user, and company. Data can be transferred to a PC via the opto-isolated PC interface via the RS232 or USB ports and HI 92000 software (optional).
