EPA Compliant Benchtop Turbidity and Chlorine Meter

The HI83414 is a multi parameter benchtop meter that measures the most important parameters in drinking water: turbidity and chlorine. The instrument is based on a state-of-the-art optical system which provides accurate results by minimizing stray light and color interferences. Periodic calibration with the supplied standards compensates for any variations in intensity of the tungsten lamp. The colorimeter portion of the meter uses a 525 nm narrow band interference filter for maintaining the proper wavelength in the measurement of free and total chlorine. All measurements are performed with 25 mm round cuvettes composed of special optical glass to ensure maximum repeatability of turbidity and chlorine measurements.

Features at-a-glance

Four Measurement Modes - The HI83414 features four measurement modes including ratio or non-ratio mode for turbidity, free chlorine, and total chlorine. In ratio mode the turbidity is 0.00 to 4000 NTU (Nephelometric Turbidity Units) while in the non-ratio mode the range is 0.00 to 40.0 NTU. The range for free or total chlorine measurements is 0.00 to 5.00 mg/L (ppm) range.Multiple Turbidity Units of Measure - Turbidity can be displayed as nephelometric turbidity units (NTU), European Brewing Convention units (EBC) or Nephelos units. EPA Compliant - The HI83414 meets and exceeds the requirements of EPA and Standard Methods both for turbidity and colorimetric chlorine measurements. When the meter is in EPA mode all turbidity readings are rounded accordingly to meet reporting requirements.Calibration – A two, three, four, or five-point turbidity calibration can be performed by using the supplied (<0.1, 15, 100, 750, and 2000 NTU) standards. Calibration points can be modified if user-prepared standards are used. For free and total chlorine, the CAL Check™ standard can be used for calibration to 1.00 mg/L (ppm).AMCO AEPA-1 Primary Turbidity Standard - The AMCO AEPA-1 supplied standards 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 stable and reusable with a long shelf life.CAL Check ™ – With the powerful CAL Check™ function, reliable performance of the chlorine colorimeter can be validated at any moment by using the exclusive HANNA ready-made, NIST traceable standards. All standards are supplied with a Certificate of Analysis (COA) for traceability.GLP Data – The HI83414 features complete GLP (Good Laboratory Practice) functions that allow traceability of the calibration conditions. Data includes calibration points, date, and time.Data Logging – Up to 200 measurements can be stored in the internal memory and recalled at any time.Data Transfer – For further storage or analysis options, logged data can be downloaded to a Windows compatible PC using the USB port and the HI92000 software.Tutorial Mode - The unique tutorial mode provides additional information to help the user during measurements. When enabled, the instrument displays explanations and a confirmation button when a preparation or other operation has to be performed.Contextual Help – Contextual help is always available through a dedicated HELP button. Clear tutorial messages and directions are available on-screen to quickly and easily guide users through setup and calibration. The help information displayed is relative to the setting/option being viewed.Backlit Graphic LCD Display – A graphic LCD display provides an easy to understand, user-friendly interface. All messages are in plain text making them easy to read.
