The HI-96759 is a handheld maple syrup transmittance analyser that has a tungsten lamp with a narrow band interference filter to isolate the 560nm wavelength.
The photometer uses 10mm disposable sample cuvettes and is calibrated to 100% transmittance with a glycerol standard. All samples are compared to the glycerol standard and readings are displayed as % transmittance. With its advanced optical system, the highly precise meter eliminates subjectivity to provide readings that are accurate and repeatable.
When choosing a maple syrup, it is important to consider its clarity along with colour and taste - a light, clear syrup has a high level of quality and is indicative of a very pure product. A dark, cloudy syrup is less desirable, owing to the presence of impurities and suspended solids.
In general, maple syrup is classified into different standards based on colour and clarity. Lighter, clearer syrups are produced earlier in the season, while darker syrups are produced later in the season. The lightest grade is characterised by its very pale colour and has a light transmittance equal to or greater than 75%. The darkest grade has a light transmittance of less than 25%. The grade of maple syrup can be determined by using a photometer that measures how much light is transmitted through the syrup at a particular wavelength.
