pH Meter HI 5221

Single-channel pH meter for laboratory with color display 

pH, Redox, and temperature measurement

The pH meter HI 5221-02 is designed with the latest technology for the highest standards in the laboratory and research field. The pH meter has a large enhanced backlit color LCD graphical display, with easy, simple, and direct handling for convenience. The HI 5221-02 pH meter performs more comprehensive and accurate pH measurements due to its millisecond resolution and a wide measurement range (-2 to 20 pH units). It has maximum versatility in pH calibration between 1 and 5 points to choose from 8 standard patterns and 5 user-configurable points. The electrode diagnostic function is performed during calibration to ensure its use under optimal conditions. Connection to the PC can be done via both RS-232 and USB, and it has a large memory capacity; finally, it can be said that it is a good solution for pH measurement in the laboratory.
