Benchtop pH/mV Meter with Manual Calibration

This 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. These meters are supplied with the HI1332B PEI plastic body, double junction, gel filled pH electrode.

This is a basic affordable pH/mV benchtop meter. Operation is simplified to calibration and mode selection (pH, mV, or temperature) (640-370-04 is able to connect 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. This meter 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.
