Details
The HN/022091-01 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.
TheHN/022091-01 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
Analog Output
- The HN/022091-01 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 HN/022091-01
- This simple feature allows demonstration of the concepts of offset and slope
- The HN/022091-01 can be calibrated to any value within the measurement range of 0.00 to 14.00 pH
HN/01332B pH Electrode -
- The HN/022091-01 is supplied with the HN/01332B 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 HN/01332B 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 HN/022091-01 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
