Details
The HN/009124 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.
TheHN/009124 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.
Features at-a-glance
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 HN/009124 is supplied with the HN/01230B 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 HN/01230B is gel filled and requires no refill electrolyte solution to maintain
Temperature Compensation
- The HN/009124 offers automatic or manual temperature compensation of pH measurements over a wide range from -20.0 to 120.0°C
Measurement Recall
- The HN/009124 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 HN/009124 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
