Details
The HN/002210-02 is a basic affordable pH benchtop meter.
Operation is simplified to calibration, pH and temperature readout, and a last stored reading feature.
To enter calibration mode the user simply presses the “CAL” button.
The HN/002210-02 can be calibrated to 1 or 2 points using the 5 pre programmed buffers (4.01, 6.86, 7.01, 9.18, and 10.01).
Once a buffer is recognized and the reading is stable the meter will display “CFM” for confirm. The “CFM” key is pressed and the reading is stored.
The HN/002210-02 has two separate inputs for a BNC pH electrode and thermistor temperature probe.
The BNC connector is a universal connector that is commonly available and allows the user to select from a wide variety of pH electrodes for their particular application.
The separate temperature probe provides for a high 0.5°C accuracy measurement for precise temperature compensation.
Features at-a-glance
Simple User Interface
- Operation is simple with limited features that only require the use of a couple of buttons. Readings are easy to view on the large, clear display
One or Two-Point Calibration
- Automatic calibration can be performed at 1 or 2 points using the 5 preprogrammed buffers (4.01, 6.86, 7.01, 9.18, and 10.01)
HN/01131B pH Electrode
- The HI2210 is supplied with the HN/01131B glass body, double junction, refillable pH electrode with an indicating sensor made of High Temperature (HT) glass
- The double junction and HT glass design allows the HN/01131B to be used in a wide variety of application from samples with metals and Tris buffer to samples at elevated temperatures
Temperature Compensation
- The HN/002210-02 offers automatic or manual temperature compensation of pH measurements over a wide range from -9.9 to 120.0°C
Stability Indicator
- The HN/002210-02features 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 HN/002210-02 has a “MEM” button to store a reading
- The reading can be recalled at anytime by pressing the memory recall “MR” button
