The HQ11D digital pH analyzer can be used with any standard pH IntelliCAL electrode from Hash Company. HQ11D uses a lot of advanced software and technology, which is a very economical measurement method. Calibration data and calibration history can be carried along with each IntelliCAL electrode, allowing operators to switch calibrated electrodes between analyzers. The electrodes should be calibrated in a controllable environment and can be used on-site. Automatic detection of standard procedures and calibration reminders can ensure the accuracy of data. It can store a total of 500 data records by linking each measured sample ID, user ID, and electrode serial number.
