Description
Pocket pH measurement with a replaceable electrode
The HI 98103 Checker conveniently checks sample pH and displays the result digitally. It is a practical instrument for regular solution checks when you want to compare batches and better understand your process. Its compact size makes it easy to keep at the workstation.
Replaceable probe and calibration
The HI 1270 electrode is included and can be replaced. A worn probe therefore need not mean replacing the whole meter. Calibration solutions are supplied; carry out manual two-point calibration as directed in the instrument instructions.
What do the specifications mean?
Resolution of 0.1 pH defines the display step, while accuracy of ±0.2 pH describes the permissible difference in the result. These are separate characteristics. For repeatable readings, calibrate, clean and store the electrode according to its instructions.
