PH Meters HI9126 HANNA

Portable pH / mV Meter with CAL Check ™

HI9126 HANNAThe HI9126 is a rugged, waterproof, portable pH and mV meter. This meter offers many features including CAL Check ™ electrode diagnostics, automatic calibration, automatic shut-off, backlit LCD display, on-screen instructions, and automatic temperature compensation. The HI9126 is supplied complete with meter, PEI plastic body, double junction pH electrode, temperature probe packaged in a durable plastic carrying case.


Tea HI9126 is a rugged, portable pH and mV meter designed to provide accurate laboratory and accurate 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 includes Hanna's exclusive CAL Check ™ technology. CAL Check ™ monitors the pH bulb every time the instrument is calibrated. In the event of a dirty pH electrode, CAL Check ™ warns users that maintenance may be needed.

Calibrated buffers are continuously displayed in measurement mode to remind users of the instrument's calibration point. Users can easily determine if readings are too far outside the calibration range. The HI9126 can read and store at a touch of a button and features a real-time clock.

HI9126 utilizes the HI1230B double junction. pH electrode. Double junction design helps minimize junction contamination for consistently accurate results. The HI9126 also measures the ORP in mV range using an optional ORP probe.

Features at a Glance

CAL Check Electrode Diagnostics - CAL Check ™ monitors the condition of the pH electrode's offset and slope characteristics. Các tính theo dõi được xác định theo các voltages generated in 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 7 pre buffered programs (1.68, 4.01, 6.86, 7.01, 9.18, 10.01, 12.45) và 2 custom buffers.

X-RANGE (disabled) 0 14 đặt thời gian sau đó trong khoảng thời gian đã chọn.

On-Screen Instructions - Clear and easy to use on-screen instructions take you through all 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 the contamination of the inner reference cell which could cause precipitation of the Ag / AgCl electrolyte resulting in a clogged junction. HI1230B is gel filled and requires no 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 mode mV that can be used with a wide variety of ORP electrodes for monitoring oxidation reduction potentials.

Stability Indicator - The HI9126 features a indicator. An hourglass appears when there is instability in the reading. The hourglass disappears once the reading has stabilized. At the 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 có thể điều chỉnh tự động tự động. Mộng được đặt thành tự tắt sau khi 20 phút để gỡ bỏ các bộ nhớ tạm động của máy điện hoặc nó sẽ bị tắt cho người dùng có thể tắt độ đếm tắt với máy điện.

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