HI22091-01

Description

The HI22091 is a basic, affordable pH/mV benchtop meter with analog output 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 HI22091 is supplied with the HI1332B PEI plastic body, double junction, gel filled pH electrode.

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

The HI22091 is a basic affordable pH/mV benchtop meter. Operation is simplified to calibration, mode selection (pH, mV, or temperature), and connection to a recording device via analog output. 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.

  Features at-a-glance :

Analog Output
•  The HI22091 benchtop meter features an analog output that allows connection between the meter and a recording device.

  Built-In Solution Holders
•  The HI22091 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.

  HI1332B pH Electrode
•  The HI22091 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.

  One or Two-Point Calibration
•  Manual calibration can be performed at 1 or 2 points on the HI22091. This simple feature allows demonstration of the concepts of offset and slope.
•  The HI22091 can be calibrated to any value within the measurement range of 0.00 to 14.00 pH.

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.

Temperature Compensation
•  Manual temperature compensation provides the ability to demonstrate the effect of temperature on pH measurements.
•  Manual correction for temperature with the HI22091 is simple to use and allows for temperature corrections ranging from 0 to 100°C based on the sample being tested.
