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
