Drop a sample with a pipette; small volumes as 0.1 mL can be measured. Using sampling sheet B, volumes down to 0.05 mL can be tested.
When you're in the lab, you can test the sample in a beaker. Ensure the sensor guard sliding cap is open.
Use as a scoop to test water from a river. Vertical scoop is available with a unique sensor guard.
The sampling sheet allows tiny, trace volumes to be analysed. For example, wipe off the surface of the skin with a sampling sheet soaked with pure water and measure.
Foods containing some moisture can be tested by placing a small piece directly onto the sensor.
LAQUAtwin meters can also test dry powders. Simply place the powder sample onto the sensor, and add an appropriate amount of pure water.
Paper, textiles and films
To test sheets of paper and textiles, cut up the sample into small pieces and place them directly onto the sensor then add a defined amount of pure water.
