ZDThe series of intelligent turbidity meters adopt the principle of scattered light, and their calibration solution uses the internationally widely used standard solution of fumarate hydrazine. It is a precision and intelligent instrument that measures turbidity with good linearity, accurate and reliable values, and easy operation.

Operation steps

Before measuring the turbidity of a solution, the instrument must be calibrated.

1Correction

Power on and enter the main interface menu window. Use the "Switch" button to select the "Calibration" option. At this moment, the instrument displays that it has been inserted0000NTUTurbidity liquid, open the sliding cover panel above the machine and install theSample bottle for zero turbidity waterPlace it in the measuring pool, cover it with a sliding cover, and press the "confirm" button when the value stabilizes. Place the prepared calibration solution in sequence according to the prompts. Press the 'Confirm' button to end. Enter the main menu selection. Or press the "Switch" button to force exit, and save the previously calibrated data when exiting. Enter the main menu interface.

Attention: Clean the water stains and fingerprints on the bottle wall of the sample bottle every time, leaving no traces to avoid affecting the measurement accuracy. Try to place the sample bottle in the same direction and position as much as possible in the measuring cell each time.Please use the same sample bottle for accuracy and measurement to reduce the inaccuracy of data values caused by errors in the sample bottle.

2Turbidity measurement

In the main interface menu window, select the "Measurement" option by pressing the "Switch" button.

Pour the sample to be tested into a clean sample bottle and transfer the sample to be testedThe sample bottlePlace it in the measuring pool, cover it with a sliding cover, and the value displayed by the instrument is the turbidity value of the liquid to be measured.

3Save and extract usage methods

During the measurement process, the measured values can be saved. Press the 'Save' button to store up to10Group data. Exit and save. Press the "Confirm" button to return to the measurement state.
