产品介绍

  1.Summary

  QT-2204 sodium ion meter is a 31/2 decimal digital display of high precision sodium ion activity meter (abbreviation as instrument).It can be matched with the electrode of sodium ion selective electrode and reference electrode, and accurately measure the electromotive force produced by electrode in aqueous solution.The negative logarithm (PNa) value of sodium ion concentration can be read directly from the instrument.


The instrument has a temperature compensator,slope calibration, positioning calibrator and positioning calibration of compensator (positioning coarse), slope compensator calibration (slope coarse)
