Details
The HN/002211-02 is a basic affordable pH/mV benchtop meter.
Operation is simplified to calibration, mode selection (pH or mV), and a last stored reading feature.
The HN/002211-02 has a selection to choose between pH and mV modes.
The mV mode is used with an optional ORP electrode that is used to check the oxidation or reduction potentials of a solution.
HN Series offers a variety of ORP electrodes from glass to PEI plastic body styles.
The mV mode of the HN/002211-02 is also useful in checking the offset and slope of the pH electrode.
Understanding the offset and slope characteristic is helpful in knowing if the probe is functioning correctly.
The HN/002211-02 has a 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 and ORP 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 HN/002211-02 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/002211-02 offers automatic or manual temperature compensation of pH measurements over a wide range from -9.9 to 120.0°C
mV mode
- TheHN/002211-02 has a mV mode that can be used with a wide variety of ORP electrodes
- The mV mode is also useful in checking the offset and slope of the pH electrode
- Understanding the offset and slope characteristic is helpful in knowing if the probe is functioning correctly
Stability Indicator
- The HN/002211-02 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 HN/002211-02 has a “MEM” button to store a reading
- The reading can be recalled at anytime by pressing the memory recall “MR” button
