Description
Overview
GAOTek Portable Turbidimeter has an innovative mode called Rapidly Settling Turbidity. This provides accurate measurements for difficult-to-measure, rapidly settling samples. An exclusive algorithm that calculates turbidity based on a series of automatic readings eliminates redundant measurements and estimating. It provides convenient data logging up to 500 measurements are automatically stored in the instrument for easy access and backup. Stored information includes date and time, operator ID, reading mode, sample ID, sample number, units, calibration time, calibration status, error messages, and the result.
There is also the benefit of simple data transfer with a USB + Power Module. This does not require additional software and all data will be transferred to the module in XML format. The data can be easily downloaded to your computer with a USB connection, providing superior data integrity
