HANNA HI88703-01 EPA Compliant Benchtop Precision Turbidity Meter, Extended Range, Electrical: 115V

The HI 88703 turbidity meter is designed for water quality measurements and provides readings on low turbidity. The HI 88703 meets and exceeds the requirements of USEPA and Standard Methods. This turbidy meter's optical system guarantees accurate results, assures long term stability and minimizes stray light and color interferences. It also compensates for variations in intensity of the lamp, making no need for frequent calibration. The 25 mm round cuvets made from special optical glass guarantee the repeatability and consistency of the measurements.Turbidity measurements can be made in the 0.00 to 4000 NTU (Nephelometric Turbidity Units) range when ratiometric measurements are used and in the 0.00 to 40.0 NTU range when non ratio method is used. The instrument has an EPA compliance reading mode which rounds the reading to meet EPA reporting requirements. Alternative EBC and Nephelos measuring units are available. Depending on the measured sample and needed accuracy, normal measurement, continuous measurement or signal averaging measurement can be selected. A two, three, four or five-point calibration could be performed by using the supplied (<0.1, 15, 100, 750 and 2000 NTU) standards. When user prepared standards are used, the calibration points can be modified.HI 88703 has complete G.L.P. (Good Laboratory Practice) functions that allows traceability of the calibration conditions. The last calibration points, time and date can be checked. HI 88703 has a user-friendly interface with an easy to understand, graphical LCD. All messages are in plain text, easy to read and understand. Comprehensive contextual help is available at a simple key press. All messages and helps are available in several languages. Confirmation and error acoustic signals help the user during instrument operation. Furthermore, a tutorial mode of operation guides the user step by step through the analysis process. This turbidity meter's logging function provides up to 200 measurements can be stored in the internal memory and consulted at any time. In order to further store or analyze, the data can be downloaded to a PC using the USB port. Power: 115V. Hanna #: HI 88703-01.
