Hanna Instruments HI5222 Laboratory Research Grade Two Channel Benchtop pH/mV/ISE Meter

Features at-a-glance

Highly Customizable User Interface – The HI5222’s user interface enables the user to display measurements in a variety of modes, including real-time graphing, basic measurement with or without GLP information, and data logging. Fast, moderate, and accurate are all possible adjustments for the calibration stability requirements. Programmable alarm thresholds can be set inside or outside the permitted bounds.

Color Graphic LCD – A colour graphic LCD with on-screen help, graphics, and personalised colour settings is a feature of the HI5222. Real-time graphing is possible because to the display, and the user interface is simple thanks to the usage of virtual keys.

Capacitive Touch – Sensitive capacitive touch buttons on the HI5222 allow for precise typing when browsing menus and screens. In addition to four virtual keys that alter dependent on use, there are four dedicated keys that are utilised for routine tasks including calibration and changing measurement modes. The capacitive touch technique makes sure that sample residue never accumulates on the buttons.

Two Galvanically Isolated pH/ORP/ISE Channels – Two input channels of the HI5222 can be used to connect pH, ORP, and ISE electrodes. Connectors for BNC probes, reference probes, and temperature sensors are available on each input channel. Since each channel is galvanically isolated, no voltage interference will occur if two measurement probes are present in the same solution at the same time.

Choice of Calibration – With a choice of eight standard buffers and up to five bespoke buffers, there are choices for automated buffer recognition, semiautomatic, and direct manual entry pH calibration for up to five points.

GLP Data – A GLP feature on the HI5222 enables users to quickly view calibration data and calibration expiration information. The date, time, calibration buffers, electrode offset, and slope parameters are all included in the calibration data.

CAL Check™ – Users are warned about potential issues by CAL CheckTM when the pH electrode is being calibrated. As a percentage depending on the offset and slope characteristics, indicators include “Electrode Dirty/Broken,” “Buffer Contaminated,” electrode response time, and overall probe condition.

ISE Measurement with Choice of Concentration Units – The HI5222 offers calibration capabilities as well as readings in a variety of concentration units. You can choose from ppt, g/L, mg/mL, ppm, mg/L, g/mL, ppb, g/L, mg/mL, M, mol/L, mmol/L,%w/v, and a user-defined unit for concentration measurements.

ISE Measurement with Incremental Methods – The HI5222 comes pre-programmed with the incremental known addition, known subtraction, analyte addition, and analyte subtraction procedures. Simply follow the instructions on the screen, and the metre will make the calculation automatically, providing greater accuracy than a direct ISE measurement.

Data Logging – On the HI5222, there are three configurable logging modes: automatic, manual, and AutoHold. 100 lots of automatic and human logs, with a maximum of 50,000 records per lot and 100,000 total data points per channel. The ability to record data in accordance with sampling interval and period is provided via automatic logging.

Data Transfer – Using a USB cable and the HI92000 software, data can be transferred to a PC (both sold separately).

Contextual Help – An exclusive “HELP” key is always available to provide contextual assistance. Users can easily and quickly follow on-screen tutorial messages and instructions to complete setup and calibration. The assistance text is specific to the configuration or option being looked at.
