Measurements
  Drops
Drop a sample with a pipette, small volume as 0.1mL can be measured. Using sampling sheet B (optional), volumes down to 0.005 mL can be tested.
Immersion
When you're in the lab, you can test the sample in a beaker. Ensure the sensor guard sliding cap is open.
Scoop
Use as a scoop to test water e.g. from a river. Vertical scoop from a aquarium is also
available with unique sensor guard.
Wipe
The sampling sheet allows tiny trace volumes to be analyzed. For example, wipe off the surface of the skin with a sampling sheet soaked with pure water and measure.
 

Measurements
  Solid Samples
Foods containing some moisture can be tested by placing a small piece directly onto the sensor.
Powders
LAQUAtwin meters can also test dry powders. Simply place the powder sample onto the sensor and drop on a constant amount of pure water.
Paper, textiles and films
To test sheets of paper and textiles, cut up the sample into small pieces and place directly onto the sensor. Drop on a constant amount of pure water.
