Even if you drop it in the water, there is nothing
to fear. Its waterproof structure makes the Twin ideal for carefree
outdoor use and expands in one stroke the scope of pH measurement
activities. *impervious to water for 30 minutes
up to a depth of 1 meter. Proper function is not assured if immersed
deeper than 1 meter.
Immersion measurement To take measurement of water guality in rivers or lakes, just immerse the sensor in the water and note the measurement results.
Scoop measurement For hard to reach places, just immerse the sensor in the solution and the sensor guard will scoop up a sample. Lay the Twin flat to measure.
Flat measurement
To measure solids or powders
Just place the sample directly on tye sensor. Before measuring earth, powder, and other solid samples with low moisture content, add a drop or two of deionized water.
To measure in drops
Use a eye-dropper to drop about 0.1 mL of the sample solution on the sensor.
To measure rigid surfaces
To measure surface pH, wipe the surface of the sample with a sampling sheet dampened with deionized water and place the sheet on the sensor.
