Iron Low Range Portable Photometer$355.00
Note: Limited Quantities Available, While Supplies Last
The HI96746 Iron Low Range Photometer combines accuracy and ease of use in an ergonomic, portable design. Using the HI93746-0 ready made reagents the user can accurately determine the concentration of iron in freshwater samples within a 0.00 to 1.60 mg/L (ppm) range. The HI96746 offers many advanced features including the exclusive CAL Check™ function used for performance verification and calibration of the meter.
- CAL Check™ Validation and Calibration option
- Built-in timer for appropriate reaction interval
- Ready-made reagents ordered separately

The HI96746 portable photometer is for the measurement of iron in freshwater samples. Hanna's portable photometers feature an advanced optical system; the combination of a special tungsten lamp, a narrow band interference filter, and silicon photodetector ensure accurate photometric readings every time. The Hanna exclusive CAL Check™ feature utilizes ready-made, NIST traceable standards to verify both meter validation and calibration. The exclusive cuvette locking system ensures that the cuvette is inserted into the measurement cell in the same position every time to maintain a consistent path length.
CAL Check™ - Allows for performance verification and calibration of the meter using a CAL Check™ NIST traceable secondary standard.
GLP - Records the date of the last user calibration performed.
Built in timer - Allows the use of a timer to ensure the appropriate 3 minutes and 30 seconds reaction time is used for the chemical reaction. At the end of the timer countdown the meter will automatically take the reading. This feature ensures consistency across multiple users.
Indexing indent on meter - The meter has an indent that allows for a lock and key fit with the cuvette cap. This ensures that the cuvette is indexed consistently (same position) in order to maintain the same path length for accurate results.
Cooling Lamp Indicator - It is necessary to maintain a consistent temperature of the optical components in order to maintain a narrow wavelength band of light. This photometer has a cooling lamp indicator that is displayed for a short period of time before each measurement in order to allow the components to cool and obtain the highest accuracy possible.
Error messages - Messages on display alerting to problems including no cap, over range and under range readings, and light source error.
Auto-shut off - Automatic shut off after 10 minutes of non-use when the meter is in measurement mode. Prevents wastage of batteries in the event the meter is accidentally not turned off.
Battery status indicator
The instrument has a battery level indicator to display remaining life as follows:
- 3 lines for 100 % capacity
- 2 lines for 66 % capacity
- 1 line for 33 % capacity
- Battery icon blinks when the capacity is less than 10 %.
Units of measurement - Appropriate unit of measurement is displayed along with reading.
Iron is naturally present in water in low concentrations, but it reaches high concentrations in wastewater effluents. The iron concentration in water needs to be monitored because it becomes harmful above certain levels. In domestic water, for instance, iron can unpleasantly alter the taste, stain laundry, damage kitchenware and favor the growth of certain bacteria. Iron is also an indicator of ongoing corrosion in water cooling and heating systems. Moreover, iron is normally monitored in mining wastewater to avoid contamination.
The HI96746 uses an adaptation of TPTZ method to measure iron concentrations in the 0.00 to 1.60 mg/L (ppm) range. The reagent when added to a sample containing iron will turn the sample a violet hint; the greater the concentration, the deeper the color. The associated color change is then colorimetrically analyzed according to the Beer-Lambert Law. This principle states that light is absorbed by a complementary color, and the emitted radiation is dependent upon concentration. For iron, a narrow band interference filter at 525 nm (green) allows only green light to be detected by the silicon photodetector. As the change in color of the reacted sample increases, absorbance of the specific wavelength of light also increases, while transmittance decreases.
The HI96746 is available as a kit (HI96746C) which includes:
- Portable Photometer
