Hanna HI9124 Waterproof Portable pH Meter

The HI9124 is a rugged, portable pH meter designed to provide laboratory precision and accuracy under harsh environmental and industrial conditions. The meter offers a variety of features including automatic calibration to 1 or 2 points, automatic temperature compensation, backlit LCD, on-screen instructions, and battery error prevention system.

The HI9124 uses the universal BNC probe input for pH 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 oC accuracy measurement for precise temperature compensation.

One or Two-Point Calibration - Automatic calibration can be performed at 1 or 2 points using the 5 pre programmed buffers  (pH 4.01, 6.86, 7.01, 9.18, and 10.01).

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 HI9124 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 HI9124offers automatic or manual temperature compensation of pH measurements over a wide range from -20.0 to 120.0°C.

Measurement Recall - The HI9124 has a “MEM” button to store a reading. The reading can be recalled at anytime by pressing the memory recall “MR” button.

Automatic Shut off - The HI9124 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.
