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 is inserted into the measurement cell in the same position every time to maintain a consistent path length.

About the HI-83730-02 Photometer for Peroxide Value in Olive Oil, 230V

• 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 colour and imperfections in the oil sample before reagent addition.
• GLP
  – Review of the last calibration date.
• 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 message
  – Messages on display alerting to problems including no cap, high zero, and standard too low.
• Units of measurement
  – Appropriate unit of measurement is displayed along with the reading.

About edible oils

Over time, edible oils may degrade and spoil. The primary cause of edible oil degradation is oxidation. As oil oxidation occurs, flavours and odours can change, resulting in a product that is undesirable to consumers. The unsaturated fatty acids found in oils reacts 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.
