Hanna Instruments HI93414-11 Cal Check Calibration Set, For Free and Total Chlorine

The Hanna Instruments HI 93414-11 calibration set is used for calibrating a free/total chlorine meter at two points. The set consists of <0.10 Nephelometric Turbidity Units (NTU) and 1.00 milligram/litre (mg/L) chlorine primary standards in calibration cuvettes. The HI 93414-11 is an accessory for use with the Hanna Instruments HI 93414 portable turbidity and free/total chlorine meter, which is used to test drinking water and ambient water to meet government standards, and to monitor water used in the manufacture of food and beverages.

Turbidity meters (also called turbidimeters) determine the concentration of solids in a sample of liquid (usually water). Turbidity is the cloudiness of a liquid caused by the presence of suspended solids (particles) that may include microorganisms, yeast, or sediment. Turbidity meters indirectly determine the concentration of these solids by measuring the light scattered by particles in the sample. Turbidity meters are commonly used to test drinking water, environmental water, and water used for food and beverages for compliance with government standards.
