Benchtop pH/mV Meter with Manual Calibration - HI2209

The HI2209 is a basic, affordable pH/mV benchtop meter designed for simplicity of use. Manual calibration can easily be performed to 1 or 2 points with the help from the meter’s built-in solution holders. The meter has a large, easy-to-read LCD that displays pH or mV readings that are manually compensated for temperature variations. The HI2209 is supplied with the HI1332B PEI plastic body, gel filled, double junction pH electrode.

  • Large, Clear Display
  • Universal BNC Connection
  • Built-In Solution Holders


The HI2209 is a basic affordable pH/mV benchtop meter. Operation is simplified to calibration and mode selection (pH, mV, or temperature). The pH calibration is made simple through the easy-to-operate front panel knobs for offset and slope adjustment. A front knob is also provided to manually set temperature compensation of the pH reading.

The HI2209 has an input for a BNC electrode. The BNC connector is a universal connector that is commonly available and allows the user to select from a wide variety of pH or ORP electrodes for their particular application.

Features at-a-glance

Simple User Interface – Operation is simple with limited features that only require the use of several front panel knobs. Readings are easy to view on the large, clear display.

One or Two-Point Calibration – Manual calibration can be performed at 1 or 2 points on the HI2209. This simple feature allows demonstration of the concepts of offset and slope. The HI2209 can be calibrated to any value within the measurement range of 0.00 to 14.00 pH.

HI1332B pH Electrode – The HI2209 is supplied with the HI1332B plastic PEI body, double junction pH electrode with an indicating sensor made of General Purpose (GP) glass. The durable body and GP glass design allows the HI1332B to be used in a wide variety of applications, from chemical samples to field use and quality control.

Temperature Compensation – Manual temperature compensation provides the ability to demonstrate the effect of temperature on pH measurements. Manual correction for temperature with the HI2209 is simple to use and allows for temperature corrections ranging from 0 to 100℃ based on the sample being tested.

Built-In Solution Holders – The HI2209 benchtop meter features solution holders built directly into the casing. This convenient feature saves valuable benchtop space and maintains solution bottles in an upright position, avoiding any potential spills.
