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.

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
