GD-226 High Performance Both Positive and Negative Ion Meter

Functions:

1.Large LCD touch screen and English operation interface

2.Support multiple common ion mode (such as H+,Ag+,Na+,K+,NH4+,Cl-,F- etc…). The user can define specific ion mode and test other ions.

3.It can measure pH value, and several kinds of buffer solutions can be selected to have one-point or two-point (up to5-point calibration. )

The user can establish standard buffer groups and the meter can recognize 10 kinds of buffer solutions.

4.The test results can be stored, deleted, viewed, printed or transmitted to PC.

It can store up to 350 sets of measuring results. For other ions, the user can

store up to 100 sets of pX measuring results and 100 sets of concentration

measuring results.

5.It is equipped with RS-232 and USB port. If matched with specific data

collecting software, it can be connected with PC.
