Hanna Instruments HI740234 Replacement Tungsten Filament Lamp for EPA Turbidimeter

The Hanna Instruments HI 740234 tungsten filament lamp is a replacement light source for USEPA 180.1 compliant turbidity meters. The HI 740234 is for use with the Hanna Instruments HI 88703, HI 83414, and HI 83749 turbidity meters, which are 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.

Hanna Instruments manufactures analytical instrumentation and supplies, including pH meters, electrodes, chemical reagents, and buffer solutions. The company, founded in 1978 and headquartered in Woonsocket, RI, meets International Organization for Standardization (ISO) standard 9001.
