Details

The HI9126 is a rugged, portable pH and mV meter designed to provide laboratory precision and accuracy under harsh environmental and industrial conditions. The meter offers a variety of features including CAL Check™ electrode diagnostics, automatic calibration to 1 or 2 points, automatic temperature compensation, backlit LCD, on-screen instructions, and battery error prevention system.

The HI9126 has selectable pH and mV modes. The mV mode is used with an optional ORP electrode for the determination of oxidation or reduction potentials of a solution. Hanna offers a variety of ORP electrodes from glass to PEI plastic body styles.

The HI9126 uses the universal BNC probe input for pH and ORP electrodes. The universal BNC connector allows the user to select from a wide variety of electrodes based on their particular application. A separate RCA connector is used for a thermistor temperature probe. The temperature probe provides for a high ±0.4°C accuracy measurement for precise temperature compensation.

Features at a Glance

CAL Check Electrode Diagnostics – CAL Check™ monitors the condition of the pH electrode’s offset and slope characteristics. These characteristics are determined by the voltages generated in the calibration buffers. As part of the Cal Check feature the meter will display “clean” when the pH electrode needs to be cleaned.

One or Two-Point Calibration – Automatic calibration can be performed at 1 or 2 points using the 7 pre programmed buffers  (pH 1.68, 4.01, 6.86, 7.01, 9.18, 10.01, and 12.45) and 2 custom buffers.

Calibration Time-out – A selectable interval from 0 (disabled) to 14 days can be set in which after the selected interval the meter will display “Cal Due”.

On-Screen Instructions – Clear and easy to use on-screen instructions take you through all of the steps in performing a calibration and taking measurements.

Durable Plastic Body pH Electrode – The HI9126 is supplied with the HI1230B PEI plastic body, double junction pH electrode that is gel filled. The PEI body offers excellent chemical resistance to many harsh chemicals.  The double junction design helps minimize contamination of the inner reference cell which could cause precipitation of the Ag/AgCl electrolyte resulting in a clogged junction. The HI1230B is gel filled and requires no refill electrolyte solution to maintain.

Temperature Compensation – The HI9126 offers automatic or manual temperature compensation of pH measurements over a wide range from -20.0 to 120.0°C.

mV Mode – The HI9126 has a mV mode that can be used with a wide variety of ORP electrodes for monitoring oxidation reduction potentials.

Stability Indicator – The HI9126 features a stability indicator. An hourglass appears on the display when there is instability in the reading. The hourglass disappears once the reading has stabilized. At that time a reading should be taken or stored.

Measurement Recall – The HI9126 has a “MEM” button to store a reading. The reading can be recalled at anytime by pressing the memory recall “MR” button

Backlit LCD – The HI9126 has a display with a backlight for easy viewing of readings in poor lighting conditions.

Automatic Shut-off – The HI9126 has an adjustable auto-off feature. The meter can be set to turn itself off after 20 minutes to prevent accidental drainage of the batteries or it can be disabled so the user has to turn the meter off with the power button.

Battery Error Prevention System (BEPS) – The Battery Error Prevention System detects when the batteries become too weak to ensure reliable measurements.
