Manufacturer: Hanna Instruments Brand: Hanna Instruments Model: HI920011

The Hanna Instruments HI 920011 5-to-9 pin RS-232 serial cable is used to connect portable turbidity meters to a PC. It has a D-sub 9-pin female connector on one end and a 5-pin Deutsches Institut für Normung (DIN) female connector on the other end. The HI 920011 is for use with the Hanna Instruments portable 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.

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 ±1% for one year. Available in one-liter bottles. Ensure accurate readings by calibrating your turbidimeter

Nephelometric or transmittance measuring-the nephelometric measurement at 90° scattered light is advantageous for lower turbidity, whereas the transmission measurement at 180° is beneficial for medium to high turbidity values: With increasing turbidity, restray and scattering effects between particles are growing bigger. The reduction of light intensity in this case leads to a more accurate result than a 90° nephelometric measurement. Therefore, lab meters for high values are equipped with several measuring options: ratio modes calculate the final result from different measured angles. For ratiometric measurements, there is no specific standard method to be followed; rather, procedures are established by the application or industry. White light has a higher sensitivity for small particles, however, the inherent coloration of the solution has a stronger disturbing effect in this case. The IR measurement is required by DIN ISO, the white light measuring by US EPA.
