Turbidity and Free/Total Chlorine Meter


The 83414 is a high accuracy, combined meter that benefits from Hanna’s years of experience as manufacturer of analytical instruments.
The HI 83414 successfully combines turbidity and colorimetric measurements to meet the needs of measuring the most important parameters of drinking water: turbidity and free/total chlorine. The meter is especially designed for water quality measurements, providing reliable and accurate readings on low turbidity and chlorine values. The 83414 meets and exceeds the requirements of USEPA and Standard Methods both for turbidity and colorimetric measurements.

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. It also compensates for variations in intensity of the lamp, making no need for frequent calibration. The 525 nm intereference filter of the colorimeter assures precise and repeatable results. The 25 mm round cuvets made from special optical glass guarantee the repeatability of the measurements.

Turbidity measurements can be made in the 0.00 to 4000 NTU (Nephelometric Turbidity Units) range when ratiometric measurements are used and in the 0.00 to 40.0 NTU range when non ratio method is used. The instrument has an EPA compliance reading mode which rounds the reading to meet EPA reporting requirements. Alternative EBC and Nephelos measuring units are available. Depending on the measured sample and needed accuracy, normal measurement, continuous measurement or signal averaging measurement can be selected.
A two, three, four or five-point calibration could be performed by using the supplied (<0.1, 15, 100, 750 and 2000 NTU) standards. When user prepared standards are used, the calibration points can be modified.

Free or Total Chlorine measurements can be made in the 0.00 to 5.00 mg/L (ppm) range. With the powerful CAL CHECK™ function, the good performance of the instrument can be validated at any moment by using the exclusive Hanna ready-made, NIST traceable standards.
A one-point calibration can be performed using the same cal check standard. The 83414 has complete G.L.P. (Good Laboratory Practice) functions that allows traceability of the calibration conditions. The last calibration points, time and date can be checked.

The 83414 has a user-friendly interface with an easy to understand, graphical LCD. All messages are in plain text, easy to read and understand. Comprehensive contextual help is available at a simple key press. All messages and helps are available in several languages. Confirmation and error acoustic signals help the user during instrument operation. Furthermore, a tutorial mode of operation guides the user step by step through the analysis process.

The instrument’s logging function offers complete information for the measurement. Up to 200 measurements can be stored in the internal memory and consulted at any time. In order to further store or analyze, the data can be downloaded to a PC using the USB port.
