Reference Electrode Potentials
The three most commonly used Reference electrodes are the Calomel, Silver/Silver Chloride and Copper Sulphate electrode systems…
Total Dissolved Solids (TDS)
Total Dissolved Solids (TDS) refers to the combined content of all inorganic and organic substances contained in a liquid.
Soil Testing
Soil testing requires some sample preparation before analysis can take place
Reference Electrodes – Operating Instructions
All EDT directION electrodes and sensors are shipped with the measuring tip covered with a soaker teat or bottle filled with the appropriate soaking solution.
Reference Electrodes: Filling & Storage Solutions
It is important to know which Filling & Storage Solutions should be used with your Reference Electrodes.
Which Reference Electrode Should I Use?
It is important to know which reference electrode to use for your application. Using the wrong electrode can ruin your results.
Multi-Parameter Meter
The QP Everything Meter has multiple modes and allows for the connection of Ion Selective Electrodes, pH Electrodes, Conductivity cells, Dissolved Oxygen Electrodes and temperature probes.
Chloride Testing After Fire Damage
Chloride testing after fire damage can accurately determine the potential for corrosion in metal structures after a fire.
The Determination of Sulphate in Water
As there is no direct measuring Sulphate ISE the analysis is performed using a sample subtraction technique with a Lead ISE as the sensor.
Aluminium testing
There is no Ion Selective Electrode for Aluminium however due to the strong reaction with Fluoride in solution an indirect method is possible using a Fluoride ISE and some prepared reagents.
