SMART 3 Colorimeter








SKU: 1910


The compact SMART3 Colorimeter is ideal for water analysis in the field or in the lab. Easy to use software allows the analyst to choose a test factor from over 75 pre-programmed calibrations for LaMotte reagent systems. The reacted sample is scanned at the optimum wavelength which is automatically selected from the multiple LED optical system. The test result is presented on a large, backlit display.  The analyst has the option of entering up to 25 additional calibrations for analysis with custom reagent systems. Test factors can be arranged in any of three sequences that can be modified at any time to meet changing testing needs. The data logger holds up to 500 time and date stamped datapoints.  A USB connection allows an interface of the colorimeter with a computer for real-time data acquisition and data transfer.
