HI 93703 PDF

Prices subjected to GST plus shipping costs. HI series are microprocessor based turbidity meters that provide laboratory accuracy for field turbidity measurements. Formazine is a very toxic, unstable substance which requires particular care: its standards have to be prepared only a few minutes before performing the calibration, and cannot be reused because of their short life. HI can be used with both standards.

While ensuring health and safety measures, Hanna Instruments is open for business as usual. The HI is a high accuracy benchtop turbidity meter used to determine the turbidity of water and wastewater with high precision in the field as well as in the laboratory.

Thank you for your interest in our products. A representative will contact you within the next 2 hours. The HI Portable Turbidity Meter is specially designed for water quality measurements, providing reliable and accurate readings, even within low turbidity ranges. The instrument is based on a state-of-the-art optical system which guarantees accurate results, assures long term stability, and minimizes stray light and color interferences.

Periodic calibration with the supplied standards compensates for any variations in intensity of the LED light source. The 25 mm round cuvettes composed of special optical glass guarantee the repeatability of turbidity measurements. Turbidity measurements can be made in the 0.

The calibration can be done using the supplied calibration solutions or user-prepared standards. A two or three-point turbidity calibration can be performed by using the supplied 0, 10, and FTU standards. These non-toxic standards are made of styrene divinylbenzene polymer spheres that are uniform in size and density.

The standards are reusable and stable with a long shelf life. At this point, the instrument can still perform approximately 50 measurements. When the battery is too low to perform reliable measurements, a message appears and the meter will automatically switch off.

Turbidity is one of the most important parameters used to determine the quality of drinking water. In natural water, turbidity measurements are taken to gauge general water quality and its compatibility in applications involving aquatic organisms.

The monitoring and treatment or wastewater was once solely based on the control of turbidity. Currently, the measurement of turbidity at the end of the wastewater treatment process is necessary to verify that the values are within regulatory standards. Turbidity of water is an optical property that causes light to be scattered and absorbed, rather than transmitted.

The scattering of light that passes through a liquid is primarily caused by the suspended solids present. The higher the turbidity, the greater the amount of scattered light. Even a very pure liquid will scatter light to a certain degree, as no solution will have zero turbidity. The ISO standard for turbidity measurement uses infrared wavelength of light that is outside the visible spectrum. The EPA method uses a tungsten lamp that produces light that contains all of the visible wavelengths of light that we see as white.

A solution that is colored will be adsorbed by a complementary wavelength of light which will affect the turbidity reading. Since the ISO method is outside the visible wavelength of light the color in the sample does not interfere with the measurement.

The USEPA prefers the tungsten lamp since it provides for better accuracy at low ranges and drinking water should not be colored. The requirements of an optical turbidity meter for the measurement of diffuse radiation used in low range measurements i. The light beam that passes through the sample is scattered in all directions. The lower detection limit of a turbidimeter is determined by stray light that is detected by the sensors but not caused by light scattering from suspended particles.

The optical system of the HI is designed to have very low stray light, providing highly accurate results for low turbidity samples. These standards are used for calibration and performance verification of the turbidity meter. Supplied with Certificate of Analysis. Kit Choose Option kit meter only. Up to three-point calibration Positive-locking cuvette system Water-resistant keypad.

Hanna HI 93703-11 Portable Logging Turbidity Meter

Be the first to review this product. Turbidity is the reduction of water clarity caused by suspended or colloidal matter or impurities. High turbidity low clarity in water is caused by suspended matter such as clay, silt, organic matter, and microscopic organisms that interfere with the passage of light through the water. The suspended particles will not settle out by gravity. Turbidity is closely related to total suspended solids. The HI enhanced version features a real-time clock and internal logging for up to measurements. HD Electric.
