One sample tube is filled with sample; another with turbidity-free water. A standard turbidity solution is added dropwise to the second tube until the turbidity in the 2 tubes match. The number of drops is multiplied by a factor to calculate the turbidity.
The Oakton T-100 turbidity meter is easy to calibrate - meter automatically prompts you to the next calibration standard. The large custom LCD displays reading and units of measure. Other features include Auto-off, diagnostic error messages, and auto-ranging function. Power saving function lets you take over 1000 readings on a single set of AAA batteries. Sealed optical system with Infrared light source delivers high accuracy across entire range. No standards included in this package. Must order separately. What's included: three sample cuvettes, a light shield cap, 10-ml silicone oil, Lint-free cloth, 4 AAA batteries, and hard carrying case. Waterproof and Dustproof with IP67-rated housing that Floats! meets performance criteria as specified by ISO 7027 (DIN EN 27027) method compliant with ASTM d6855-03 (EPA recognized) four point push-button calibration for full-range accuracy auto-ranging from 0 to 1000 NTU

Use this clear, redesigned, 60-cm tube to accurately measure the turbidity of shallow or flowing bodies of water where a Secchi disk can_t be used. A single operator controls the water-level discharge from the tube by gently pushing it against the ground to activate the stop plunger when the 45-mm Secchi-disk design is visible. This action immediately stops the flow of water to accurately and efficiently measure the water_s transparency. This unique tube features a side scale with centimeter and Nephelometric Turbidity Unit (NTU) markings (0 to 60 NTU scale).
Primary Standard Solutions can be used to calibrate nephelometers or turbidimeters. EPA-approved polymeric standards outlast Formazin standards. Suspended polymeric particles virtually never settle or clump. Solutions are guaranteed to maintain NTU values within Â±1% for one year. Available in one-liter bottles. Ensure accurate readings by calibrating your turbidimeter
