Extech ExStik II pH/ conductivity meter measures 5 parameters including conductivity, TDS, salinity, pH, and temperature using one electrode.
The EC500 ExStik II meter measures pH as well as conductivity, total dissolved solids ( TDS) , salinity, and temperature. With the EC500s dynamic cell-constant technology it is possible to measure a wide range of conductivity, TDS, and salinity with the same electrode.
The ExStik uses four CR2032 Lithium Ion Batteries. If the batteries are weak, the BAT indicator appears on the LCD. Press the ON/ OFF key to turn the ExStik on or off. The auto power off feature shuts the ExStik off automatically after 10 minutes of inactivity to preserve battery life.
