Description:
ATW2310 is a small, highly integrated marine hyperspectral radiometer produced by Aopu Tiancheng, which can monitor water colors of ultraviolet, visible, and near-infrared wavelengths.
Small size, light weight, and low power consumption make ATW2310 very suitable for handheld and remote online applications.
The ATW2310 family is specially designed to combine high-precision hyperspectral measurement with maximum flexibility. In addition, the modular measurement system reduces costs, provides numerous accessories and customized solutions.
The ATW2310 can be hoisted on a ship or column for remote online monitoring; it is especially suitable for testing in remote places, such as ocean, lake, river and other related water environment monitoring.
