The HI83730 Portable Photometer for the Determination of Peroxide Value in Oils combines accuracy and ease of use in an ergonomic, portable design. A user can accurately determine the peroxide value of olive oil within a 0.0 to 25.0 meq O2/kg range using the HI83730-20 ready made reagents.

Built-in Timer

Automatic Shut Off

Ready-made Reagents

The HI83730 portable photometer is for the determination of peroxide value in edible oils. 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 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.

Features at-a-glance

Built-in timer – Display of time remaining before a measurement is taken. Ensures that all readings are taken at the appropriate reaction intervals for the test being performed.

Zero key – A simple press of the zero key on the face of the meter will account for the color and imperfections in the oil sample before reagent addition.

Auto shut-off – Automatic shut-off after 15 minutes of non-use when the meter is in measurement mode. Prevents wastage of batteries in the event the meter is accidentally left on.

Battery status indicator – Indicates the amount of battery life left.

Error messages – Messages on display alerting to problems including no light, inverted sample, and out of range.

Units of measure – Appropriate unit of measure is displayed along with reading.

optical system

Over time, edible oils may degrade and spoil. The primary cause of edible oil degradation is oxidation; as oil oxidation occurs, flavors and odors can change, resulting in a product that is undesirable to consumers. The unsaturated fatty acids found in oils react with oxygen, creating peroxide as an unwanted byproduct. This oxidation reaction is more likely to occur under certain conditions, including exposure to light, the presence of metal ions, the introduction of oxygen, or when storage temperatures are not maintained. In order to determine oil quality and the onset of oxidation, peroxide value is determined. Peroxide value is defined as the amount of peroxide oxygen per kilogram of oil, which is reported in units of milliequivalents or meq. A lower peroxide value indicates higher quality edible oil.

The HI83730 uses an adaptation of the EC 2568/91 method and following amendments to measure peroxide values of less than 25.0 meq O2/kg. When the reagent is added to a sample containing peroxides, the sample will turn a yellow hue; 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 determination of peroxide value, a narrow band interference filter at 466 nm (blue) allows only blue light to be detected by the silicon photodetector and omits all other visible light emitted from the tungsten lamp. As the change in color of the reacted sample increases, absorbance of the specific wavelength of light also increases, while transmittance decreases.
