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.
