Thank you for selecting the waterproof portable AQ3010 turbidity
meter. The AQ3010 meter allows you to measure turbidity of an aqueous
sample in the field. This instrument operates on the nephelometric
principle of turbidity measurement and is designed to meet the criteria
specified in ISO 7027 and DIN 27027 standards. See the Measurement
Principle section.

When in measurement mode, the READ/ENTER key is used
to perform a measurement.
Single-shot measurements: When the key is pressed and
released immediately (a quick key stroke of less than 0.3
seconds), the display will blink [-Rd-] ten times and display
the measured value.
Continuous measurements: If the READ/ENTER key is
pressed and held, the instrument will perform a continuous
measurement during which the display is updated every
2 seconds. This can be used for indexing vials. (This
function is not available in calibration mode). After
the READ/ENTER key is released, the instrument will
