Product Overview

• HI96748 portable photometer is for low range measurement of manganese. 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. The dedicated cuvette locking system ensures that 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 the 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 read the reading. This feature ensures consistency between multiple users.

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

• Cooling lamp indicator - in order 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 is displayed for a short period before each measurement so that the components cool and the highest possible accuracy is obtained.

• 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 wasting battery if the meter is accidentally left on.

• Battery status indicator

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

• 3 lines, 100% capacity

• 2 lines, 66% capacity

• 1 line, 33% capacity

• When the battery is below 10%, the battery icon flashes.

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

• Manganese is one of the most common metals in nature and is used in many industrial applications, such as fertilizer production and the pharmaceutical industry. Manganese salts are also used in ferrous alloys (steel manufacturing) and non-ferrous alloys because they can improve their corrosion resistance and hardness.

• HI96748 uses the 1-(2-pyridylazo)-2-naphthol PAN method to measure manganese concentrations of less than 300μg/L (ppb) manganese. When the reagent is added to a sample containing manganese, the sample will turn orange; 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 the determination of manganese, a 525nm (green) narrow band interference filter allows only the silicon photodetector to detect green light while ignoring all other visible light emitted from the tungsten lamp. As the color change of the reacted sample increases, the absorbance of light at a specific wavelength also increases, while the transmittance decreases.
