The heavy-duty waterproof Hanna Instruments HI 9124 / HI 9125 pH meters have been designed with the latest microprocessor technology to provide laboratory results and accuracy under harsh industrial conditions. Hanna Instruments HI 9124 / HI 9125 pH meters feature large multi-level LCDs that display the pH and temperature (°C or °F) simultaneously. Graphic symbols are provided to help the user during the calibration process.

The Hanna Instruments HI 9124 / HI 9125 pH meter has an automatic pH calibration procedure with 5 standard buffer values (4.01, 6.86, 7.01, 9.18 and 10.01), buffer recognition to avoid errors, and automatic temperature compensation.

The Hanna Instruments HI 9125 pH meter can be used with ORP (Oxidation Reduction Potential) electrodes. The resolution automatically switches from 0.1 to 1 mV when the reading exceeds 700 mV.

The Hanna Instruments HI 9126 pH meter is the next generation in professional, accurate, easy-to-use pH meters. Designed to provide laboratory results in a sleek, portable design. The Hanna Instruments HI 9126 pH meter features Hanna's exclusive Calibration Check ™ technology. Calibration Check ™ monitors the pH bulb and reference junction of the electrode every time the instrument is calibrated. In the event of a dirty pH bulb, Calibration Check ™ prompts the user that additional cleaning may be needed.

The Hanna Instruments HI 9126 pH meter's extended multi-level LCD displays pH and temperature (°C or °F) readings simultaneously, while also displaying the electrode status and operational guides. The Hanna Instruments HI 9126 pH meter helps users through the calibration process with clear on-screen messages and features a series of diagnostic features to improve measurement consistency and reliability.

Ease of use and high-end features come together in Hanna Instruments' new family of pH, ISE, conductivity, and dissolved oxygen field instruments. A backlit 128 x 64 pixel graphic LCD provides a clear graphical display of measured parameters and set-up screens, and the use of dedicated and soft-keys allows fast, intuitive operation in a choice of languages. In addition, content sensitive on-screen help is always available.

For use in the field, these instruments can be easily operated with one hand and are housed in a rugged waterproof casing. The function key operation allows the user to navigate from screen to screen with immediate access to important information such as calibration status, methods set up, units and logged data.

All instruments feature log-on demand and a USB port to download stored data to a computer. Other common features include a CALIBRATION DUE warning (to prevent errors due to old calibration), auto endpoint of measurement (the instrument freezes the LCD when the reading is stable), comprehensive GLP functions, and temperature displayed in °C or °F.

Hanna Instruments HI 98180, HI 98181, HI 98182, HI 98183

Six models are available to cover all applications. All meters feature Hanna's exclusive Calibration Check ™. The pH electrode state is compated to the previous calibration and the user is warned in the event of significant changes to avoid erroneous calibration due to a bad/dirty electrode or a contaminated buffer. The electrode condition is always displayed on the LCD and the OUT OF CALIBRATION RANGE warning alerts the user if the measurement is taken too far from the calibration points.
