AQUAfast II Colorimeters

• Fast, Accurate Measurements
• Based on Standard Methods
• Economical to Operate

AQUAfast II lightweight microprocessor-controlled colorimeters weigh only 10 ounces. Eleven models allow measurement of over 20 species. The easy-to-use three-button interface ensures error-free measurements. Reagents are provided in shelf-stable, rapid-dissolving, compact tablets. Tablets are easy to add to cuvettes and eliminate any loss of powdered reagent. Sample concentration is simply read from the large, liquid crystal display (LCD). These battery-operated colorimeters are ideal for both laboratory and field use. Tests are based on methods accepted by regulatory agencies throughout the world. Single parameter units and the Drinking Water Test Kit come complete in a carrying case with reagents, cuvettes, stir rod, brush and instructions. The Multi series of units come in a carrying case with cuvettes, stir rod, brush and instructions; reagent kits must be ordered separately.

• Simple to Use
• Four Ranges from 0 to 2000 NTU
• Complete Kit includes Standards

AQUAfast II Turbidity system operates on the nephelometric principle of measurement. The photodetector is at 90° to the light scattered by the sample and the light source is an 875 nm LED. System meets ISO 7027 criteria for turbidimetric measurement and comes complete with Turbidity standards. Turbidity comes in a carrying case with four standards, sample cuvettes and instructions. Results given directly in NTU (nephelometric turbidity units).
