HI3512 is a dual-input professional pH/ORP/ISE/EC/Resistivity/TDS/NaCl/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 instruments is a dual-input model measuring pH, ORP, or ISE and temperature on channel 1 and EC, Resistivity, TDS, and Salinity (utilizing an EC probe) 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
- pH/mV/ISE and temperature measurements (Channel 1)
- EC/TDS, NaCl/Resistivity and temperature measurements (Channel 2)
