Dual-Input pH/ORP/ISE/Temperature Bench Meter with Calibration Check - HI3222

HI3222 is a professional dual-input pH/ORP/ISE/Temperature Bench Meter with a graphic LCD designed to provide high accuracy and ease of use both in the laboratory as well as in harsh industrial conditions. This instrument is a dual-input model measuring pH or ORP and temperature on channel 1 and ISE or ORP and temperature on channel 2. A Relative mV feature is also available.

This meter features Hanna’s exclusive Calibration Check™, a diagnostics system that ensures accurate readings every time. Calibration Check system eliminates erroneous readings due to dirty or faulty pH electrodes or contaminated buffer solution by alerting users of potential problems during the calibration process.

Throughout the calibration process, users are guided step-by-step by the on-screen tutorial. After calibration, a probe condition indicator is displayed on the LCD informing the user of the overall electrode status.

A variety of interactive user support is available before, during and after measurement. Onscreen tutorials guide users through set-up, calibration and measurement while context sensitive help of any screen is available at a push of a button. The HELP screen accessed by a dedicated HELP button, includes language specific assistance for menu parameters, calibration, log, contact information and accessories for your instrument.

Main Features:
• Dual-input channel model
• Up to 5 point pH calibration with 7 standard buffers and 5 custom buffers to choose from
• Messages on the graphic LCD for an easy and accurate calibration
• Diagnostic features to alert the user when the electrode needs cleaning
• Three types of logging modes (for pH, ISE and mV)
– Stability logging
– Interval logging
– Log-on-demand
• Relative mV measurements
• Log on demand up to 400 samples
• Log interval with log on stability feature up to 600 records
• Auto Hold feature, to freeze first stable reading on the LCD
• GLP feature, to view last calibration data for pH, Rel mV or ISE
• PC interface
