1. INTRODUCTION
AquaSearcher™ AP30TUR combines the scattered light method and the
transmitted light method, and uses a near-infrared light source to eliminate color
interference, which conforms to the ISO7027 standard. There are two detectors:
90° and 180° in the instrument. The 180° detector receives the transmitted light,
and the 90° detector receives the scattered light. The intensity of the scattered
light and the transmitted light is positive to the turbidity in the sample. The
intensity of light and transmitted light is used to calculate the turbidity value of the
sample.
It has the following features:
•Built-in filter to avoid background light interference.
•High-precision optical structure, accurate and stable measurement.
•Built-in high-performance micro-processing core, high data processing
power.
•Easy to use, text on the screen indicates operation instructions.
•Small size, light weight, dustproof and shockproof.

2. NOTICE
1. When holding the bottle, please take the bottle cap directly, and do not
touch the part below the line of the bottle with your hand.
2. Clean the watch surface with a lens cleaning cloth before placing the
bottle in the slot.
3. Keep the white bottle intact, without scratches, and clean inside and
outside.
4. The silk screen"▽" on the black bottle should be aligned with the "△"on
the edge of the black groove.
5. During the testing, there must be no bubbles on the inner wall of the white
bottle, otherwise the measurement accuracy will be affected, and the
bubbles can be discharged by tilting slightly.
6. When recalibrating, it is necessary to place the standard solution strictly
according to the instructions on the interface. For AP30TURL Turbidimeter
perform four calibration points of 0/1/2/100 NTU must be calibrated, and
the four calibration points of 200/400/800/1000NTU can be freely selected
and work on AP30TURH Turbidimeter
7. Please put on the shading cover before testing.
8. Avoid any liquid or foreign objects entering the detection tank. After use,
please cover the rubber sealing plug in time, and pay attention to the
direction of the sealing plug (the arrow of the sealing plug is in the same
direction as the arrow of the instrument logo).
The illustrations are for reference only.

the computer with a USB data cable, the computer will automatically
recognize the instrument and display the drive letter " AP30" on the
computer.
You can operate the instrument in the same way as the U disk. The test
record is saved in the "Record" folder. "CalibrateRecord.csv" is the
calibration data log, and "DetectionRecord.csv" is the measurement data
log. You can double-click to open and view the details or copy the data to
your computer.
Note: Do not delete the two program files under the AP30/App file.
