Product Overview

• Note: Limited quantities available, limited supply

• The HI96746 Iron low-range photometer features an ergonomic portable design that combines accuracy and ease of use. Using HI93746-0 ready-made reagents, users can accurately determine iron concentration in freshwater samples over a range of 0.00 to 1.60 mg/L (ppm). The HI96746 offers many advanced features, including a dedicated CAL Check™ function for meter performance verification and calibration.

• CAL Check™ verification and calibration option

• Built-in timer for proper reaction intervals

• Ready-made reagents ordered separately

• *Products classified as dangerous goods can only be shipped by ground transport.

• The HI96746 portable photometer is used to measure iron in freshwater samples. Hanna's portable photometers use an advanced optical system; the combination of a special tungsten lamp, narrow-band interference filter, and silicon photodetector ensures accurate photometric readings every time. Hanna's exclusive CAL Check™ feature uses ready-made NIST-traceable standards to verify meter verification and calibration. A dedicated cuvette locking system ensures the cuvette is inserted into the measuring cell in the same position every time to maintain a consistent path length.

• Features at a glance

• CAL Check™ - Allows performance verification and calibration of the meter using CAL Check™ NIST-traceable secondary standards.

• GLP - Records the date the last user calibration was performed.

• Built-in timer - Allows use of a timer to ensure the chemical reaction uses the appropriate 3 minute 30 second reaction time. When the timer countdown ends, the meter will automatically take a reading. This feature ensures consistency among multiple users.

• Indexing detent on the meter - The meter has a detent that allows a lock and key to engage with the cuvette cap. This ensures the cuvette is consistently indexed (same position) so that the same path length is maintained for accurate results.

• Cooling lamp indicator - To maintain narrow-band light, it is necessary to keep the temperature of the optical components consistent. This photometer has a cooling lamp indicator that displays briefly before each measurement so that the components can cool and the highest possible accuracy can be achieved.

• Error messages - Displayed messages warn of problems, including no cap, over-range and under-range readings, and light source errors.

• Auto shut-off - When the meter is in measurement mode, it automatically shuts off after 10 minutes of non-use. Prevents battery waste if the meter is accidentally left on.

• Battery status indicator

• The instrument has a battery level indicator to show remaining life, as follows:

• 3 bars, 100% capacity

• 2 bars, 66% capacity

• 1 bar, 33% capacity

• When the battery level is below 10%, the battery icon will flash.

• Measurement units - The appropriate measurement unit is displayed together with the reading.

• Iron occurs naturally in water at low concentrations, but at higher concentrations in wastewater. Iron concentration in water needs to be monitored because iron becomes harmful above certain levels. For example, in domestic water, iron can unpleasant change taste, stain laundry, damage cookware, and promote the growth of certain bacteria. Iron is also an indicator of ongoing corrosion in water cooling and heating systems. In addition, iron in mining wastewater is commonly monitored to avoid contamination.

• The HI96746 uses an adaptation of the TPTZ method to measure iron concentration over the range of 0.00 to 1.60 mg/L (ppm). When the reagent is added to a sample containing iron, it turns the sample purple; the greater the concentration, the deeper the color. The associated color change is then analyzed colorimetrically according to the Beer-Lambert Law. This principle states that light is absorbed by the complementary color, and the emitted radiation depends on the concentration. For iron, a 525 nm (green) narrow-band interference filter allows only green light to be detected by the silicon photodetector. As the color change of the reacted sample increases, the absorbance of light at a specific wavelength also increases, while transmittance decreases.
