PXSJ-226 ion meterDetailed product description：

The main features of PXSJ-226 ion meter are:

Touch sensitive large screen display, fully Chinese operation interface
Equipped with multi-point calibration (up to 5 points), allowing users to establish their own standard solution group function
It stores various commonly used ion modes such as H+, Ag+, Na+, K+, NH4+, Cl -, F -, etc
Measurement concentration units are converted between (0.000-19990) mg/L, mol/L, and PX
Users can create custom ion modes and also measure other ions
The measurement results can be stored, deleted, viewed, printed, or transmitted to a PC. For H+instruments, up to 150 sets of pH measurement results can be stored, while for other ions, users are allowed to store 100 sets of pX measurement results and 100 sets of concentration measurement results
Equipped with an RS-232 interface, it can be connected to a TP-16 printer to print current measurement results or stored data, and can also communicate with a computer
