HI 83414
is a high accuracy, combined meter with technology 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
HI 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, so there’s no need for frequent calibration. The 525 nm
intereference filter of the colorimeter assures precise and repeatable results.
The 25 mm round cuvettes 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 can 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 edited.
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 performance of the instrument can be validated at any
time by using the exclusive Hanna ready-made, NIST traceable standards.
A one-point calibration can be performed using the same cal check standard.
HI 83414
has complete G.L.P. (Good Laboratory Practice) functions that allow traceability of the
calibration conditions. The last calibration points, time and date can be checked.
HI 83414
has a user-friendly interface with an easy to understand, graphic LCD. All messages are in
plain text, easy to read and understand. Comprehensive contextual help is available at a simple key
press. All help information and messages 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 analytical process.
The instrument’s logging function offers complete information for all measurements. Up to 200
measurements can be stored in the internal memory and consulted at any time. In order to further
store or analyse, the data can be downloaded to a PC using the USB port.
