The 

HI96746

 

is an auto diagnostic portable microprocessor meter that benefits from  

Hanna Instruments’ years of experience as a manufacturer of analytical instruments. It has the 
advanced optical system based on a special tungsten lamp and a narrow band interference filter 
that allows most accurate and repeatable readings. All instruments are factory calibrated and the 
electronic and optical design minimizes the need of frequent calibration.
With the powerful 

CAL Check

TM

 validation function, you are able to validate good performance 

of your instrument at any time. The validation procedure is extremely user friendly. Just use the 
exclusive Hanna Instruments ready‑made, NIST traceable standards to verify the performance of 
the instrument and recalibrate if necessary.
The instrument is splash proof and the lamp and filter units are protected from dust or dirt by a 
transparent cup. This makes the instruments fulfill field applications. Display messages aid the user 
in routine operation. The meter has an auto‑shut off feature that will turn off the instrument after 
10 minutes of non use in measurement mode or after 1 hour if left in calibration mode.
The meter uses an exclusive positive‑locking system to ensure that the cuvette is in the same 
position every time it is placed into the measurement cell. It is designed to fit a cuvette with a 
larger neck making it easier to add both sample and reagents. The cuvette is made from special 
optical glass to obtain best results.
The 

HI96746

 meter measures the iron content in water samples in the 0.00 to 1.60 mg/L (ppm) 

range. The method is an adaptation of the TPTZ method.
The reagents are powder form and are supplied in packets. The amount of reagent is precisely 
dosed to ensure the maximum repeatability.
