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