Designed for portability and durability the Oakton WD-35635-00 T-100 Turbidity meter is ideal for monitoring turbidity in chemical, food and industrial applications. The microprocessor-based T-100 turbidity meter uses an infrared LED light source and delivers unprecedented repeatability and accuracy while offering resolution as low as 0.01 NTU. This lightweight meter is a valuable analytical tool for field-testing and quality control. Calibration standards are now provided in freeze-resistant 60-mL HDPE bottles for better shipping and longer shelf-life. The WD3563500 includes a collection bottle, calibration standards (0.02, 20.0, 100, 800 NTU), 3 cuvettes, a lint-free cloth, a container of silicone oil, and a hard carrying case.
