Hanna HI83414 Benchtop Turbidity and Chlorine Meter
Description
Turbidity and chlorine on one benchtop instrument
The HI83414 is a high-accuracy combined benchtop meter that joins turbidity and colorimetric measurements to cover the two parameters most watched in drinking water: turbidity and free or total chlorine. Hanna states that it meets and exceeds USEPA and Standard Methods requirements for both turbidity and colorimetric measurement.
Turbidity runs up to 4000 NTU with the ratiometric method and up to 40.0 NTU with the non-ratio method, with EBC and Nephelos units as alternatives and an EPA reporting mode. Chlorine is measured from 0.00 to 5.00 mg/L as free or total chlorine with a 525 nm interference filter that gives precise, repeatable results.

Optics, calibration and quality assurance
A state-of-the-art optical system keeps results stable, limits stray light and colour interference and compensates for variations in lamp intensity, so frequent recalibration is avoided. Round 25 mm cuvettes of special optical glass give repeatable measurements. Turbidity can be calibrated at two, three, four or five points using the supplied standards, and the points can be edited when user-prepared standards are used.
The CAL Check function validates chlorine performance at any time with ready-made NIST-traceable standards, and a one-point calibration can use the same standard. Complete GLP functions keep calibration conditions traceable. A graphic LCD, contextual help in several languages and a tutorial mode guide the operator, and 200 measurements can be logged and downloaded through USB.
Where it fits, and the standard kit
The HI83414 is a laboratory instrument for water-treatment works, distribution laboratories and municipal or industrial compliance testing, where one bench instrument must report turbidity and chlorine from the same sample desk. For field turbidity use, the HI98703 portable turbidimeter is the related Hanna model; for portable chlorine only, the HI97711.
Confirm the mains supply, the reporting unit your regulator expects, whether ratio mode is permitted by your method, and the reagent consumption. Per the manual, each HI83414 is supplied with five sample cuvettes and caps, calibration cuvettes (HI83414-11), silicone oil, a wiping cloth, scissors, a power cord, the instruction manual and the instrument quality certificate.

About brand
Hanna Instruments is a maker of analytical instruments for water and liquid testing, founded in 1978 in the Padua area of Italy by Oscar and Anna Nardo. Its early breakthrough was the pHep, an affordable pocket-sized pH tester. The company is now led by the founders' children, Martino and Pamela Nardo, with its headquarters in Woonsocket, Rhode Island, and offers more than 3,000 products.
Seven Star LLC is an independent supplier in Muscat. We list Hanna instruments for water, wastewater and laboratory users in Oman and the GCC.

Hanna product series
Portable meters include the HI98190 pH and ORP meter, the HI98192 EC, TDS and salinity meter, the HI98193 dissolved oxygen and BOD meter, the HI98199 pH, EC and DO meter and the HI9829 multiparameter water quality meter.
The HI98703 is an EPA compliant portable turbidity meter, the HI97711 a free and total chlorine photometer and the HI83414 a benchtop turbidity and chlorine meter.
Waterproof portable meters such as the HI98190 and HI98192 suit field use, with automatic temperature compensation and GLP data for audits. Turbidity measurement with the HI98703 follows EPA method 180.1, and the HI97711 photometer measures free and total chlorine for disinfection control.
Where Hanna instruments are used
Drinking water and desalination plants, wastewater treatment, environmental field surveys, aquaculture, cooling water and quality control labs.
