YSI 9500 Photometer/ Colorimeter

YSI 9500 Photometer/ Colorimeter portable photometers accurately analyze all the major inorganic constituents of water. They are rugged, fully waterproof, easy-to-use and provide quick, accurate test results.  The photometric technology uses light to measure color changes in water samples treated with a reagent.

They are accurate to +/-0.005 at 0.3 absorbency units (au) and resolution is 0.001au. The sample is simply placed in the unique adaptive cell holder and a button pressed. The cell holder automatically adjusts to various round tube sizes. The 9300 and 9500 feature automatic light wavelength selection for each of their pre-programmed test methods. They have easy-to-navigate menus and over 100 test choices, providing full flexibility. Both units are sealed to IP67 specifications and run on standard AA batteries. Each comes complete with a carry case and room to store the required reagents.
