Analog Output - The 22091 benchtop meter features an analog output that allows connection between the meter and a recording device.
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 22091. 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.
HI1332B pH Electrode - The 22091 is supplied with the 1332B 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 1332B 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 HI22091 is simple to use and allows for temperature corrections ranging from 0 to 100°C based on the sample being tested.
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.
