HACH 2100Q Portable Turbidity Meter

TURBIDITY METER Easy Calibration and Verification Be confident your measurements are right every time with on-screen assisted calibration and verification. You save time and get accurate results with an easy-to-follow interface that eliminates the need to reference complicated manuals in order to perform routine calibrations. Single-standard RapidCal™ calibration offers a simplified solution for low level measurements. Simple Data Transfer Data transfer with the 2100Q is simple, flexible, and doesn’ t require additional software. This feature requires the USB + Power module. All data can be transferred to the module and easily downloaded to your computer with a USB connection, providing superior data integrity and availability. With two different module options, you can customize connectivity and power to meet your specific needs. Accuracy for Rapidly Settling Samples The Hach 2100Q Portable Turbidimeter incorporates an innovative Rapidly Settling Turbidity™ ( RST) mode to provide accurate, repeatable 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. 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.
