Item no. HI-93102
Complete Tool for Water Analysis. It measures Free & Total Chlorine, Cyanuric Acid, pH, Iodine, Bromine, Low Range Iron and Turbidity.
The HI93102 (C-102) is a portable multiparameter meter that measures turbidity, free and total chlorine, cyanuric acid, pH, iodine, bromine, and low range iron. This meter combines accuracy and ease of use in an ergonomic, portable design. A user can accurately determine the turbidity after calibration with AMCO-AEPA-1 standards; determination of free chlorine, total chlorine, cyanuric acid, pH, iodine, bromine, and low range iron is reliable and consistent with the use of ready made reagents. HI 93102 has been designed to perform measurements according to
the USEPA’s 180.1 method and the Standard Method 2130B.
The most important parameters needed for water analysis, especially in drinking water, can be measured with Hanna’s HI93102 portable meter. This instrument not only measures turbidity, but also free and total chlorine, cyanuric acid, pH, iodine, bromine, and low range iron. Measurements are made quickly and accurately through a sophisticated, yet easy-to-use microprocessor. Users can select between pre-programmed calibration values or calibration points can be customized at a specified concentration or relative absorbance of the sample.
The HI93102 offers many features that appeal to use in the field as well as in laboratory settings. The exclusive cuvette locking system ensures that the cuvette is inserted into the measurement cell in the same position every time to maintain a consistent path length. Up to 25 measured samples can be stored in memory, together with time and date. Miniaturization of the electronics has made it possible to offer unsurpassed accuracy and quality in a portable unit weighing just one pound.
AMCO AEPA-1 Primary Turbidity Standard - The AMCO AEPA-1 standards for the turbidity range of the HI93102 are recognized as a primary standard by the USEPA. 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.
Logging – The HI93102 allows users to log up to 25 measurement readings. Measurement logs can easily be recalled with the press of a button and a reminder will appear if the memory becomes full. The logging mode can be enabled or disabled.
GLP – With a press of the “GLP” button on the face of the meter, users can view the date, time, and two calibration values of the current mode.
Auto-shut Off - Automatic shut off is selectable after 10, 20, 30, 40, 50, or 60 minutes of non-use when the meter is in measurement mode. This feature prevents wastage of batteries in the event the meter is accidentally left on.
Battery Status Indicator - The status of the battery is monitored during every measurement cycle. An indicator will warn the user when the amount of battery life left is not sufficient to take reliable measurements.
Error Codes – Helpful diagnostic codes appear on the display alerting to problems including low light, high light, or sample out of range.
Significance of Use
Turbidity, free and total chlorine, cyanuric acid, pH, iodine, bromine, and low range iron are all critical parameters that can be tested to ensure good water quality in drinking water, wastewater, and water used for pools and spas.
Turbidity is one of the most important parameters used to determine the quality of drinking water. Once considered as a mostly aesthetic characteristic of drinking water, significant evidence exists that controlling turbidity is a competent safeguard against pathogens. In natural water, turbidity measurements are taken to gauge general water quality and its compatibility in applications involving aquatic organisms.
Chlorine is one of the most commonly used disinfectants for water treatment. It can be added to in various forms including calcium hypochlorite, sodium hypochlorite, or in some instances, chlorine gas. When added to water, chlorine creates hypochlorous acid (HOCl) which dissociates into hypochlorite ion (OCl-).
