The MD600 Multi-Parameter Colorimeter is a versatile instrument that tests for a wide range of water quality parameters and is perfect for use in either the field or laboratory. Using Lovibond's “Open Reagent System” (which uses Powder Pack, stable tablets and liquid reagents) the MD600 features an industry-leading 6 LED photo detector array and supports 70 pre-programmed methods (from Alkalinity through Zinc) and 20 user defined methods. Up to 1,000 data sets can be stored in the instrument's internal memory to assure good record keeping, and can be transferred to a computer or printer with the IRiM.
