About this item
Ideal for testing water, wastes and process fluids in the lab, plant, classroom or field
Color Disc Test Kits for use with Comparator contain color disc, stable reagents for tests, dispensers, labware and easy step-by-step instructions. Color discs are non-fading and will continue to give accurate results even after prolonged exposure to sunlight, temperature extremes, excessive humidity and corrosive fumes. Chorine kits supply sufficient reagents for 50 tests; pH kits, enough for 120 tests.
Chlorine tests for free, combined and total chlorine are acceptable by EPA for NIPDWR compliance monitoring.
The comparator accepts interchangeable discs containing 9 or 10 permanent color standards. A touch of the finger brings one standard after another into view for comparison with the color of the reagent-treated sample. When the colors match, the correct test result appears in an aperture in the comparator. The magnifying prism enhances the comparison process by bringing colors side-by-side into one enlarged image for a positive color match. A precision diffuser provides equal light to the color standard and sample. The 13mm square tube shows uniform color from edge to edge. Pocket size: 9.2Wx9.2Hx3.8Dcm (35/8x35/8x11/2"). Chemical-resistant phenolic construction. Optional “Daylite” Illuminator provides correct color matching conditions at all times and locations, irrespective of lighting conditions. Features a color-correcting lamp and filter in a sloping-front housing.
