Model Fx

Accurate Measurement of the Colour of Edible Oils at the Correct Temperature Add to quotation cart

Part Number 169200


  • Avoid misreading from crystallisation
  • Measures Lovibond® RYBN, Lovibond RY10:1, AOCS RY, Chlorophyll & b-Carotene
  • Allows the Measurement of Hot Samples (Integrated Heater)
  • Ensured Compliance to Standards
The Lovibond® Model Fx solves the problem of measuring the colour of edible oils with its unique ability to not only keep the oil at a constant temperature but also to measure and report on the temperature of the sample, avoiding any misreading from crystallisation. You can now measure edible oils in their natural and correct state without any risk of the sample’s temperature affecting the results. The Model Fx measures according to the following standards: Lovibond® RYBN, Lovibond RY10:1, AOCS RY, Chlorophyll & b-Carotene


  • Edible Oils and Fats
  • Avoid Misreading from Oil Crystallisation
    Many edible oils are unique in their fractionation – resulting in different melting points for different applications.
    This makes the sample temperature, and sample heating to maintain the temperature during measurement, more important since temperature and colour go hand in hand.
    Temperature and duration times must be accurately set to ensure heating to the full liquid phase for measurement, while bearing in mind that overheating can cause the oil to turn darker. Microwave heating is faster but may not result in uniform temperatures of the oil. The integrated heater also allows the measurement of hot samples and keeps the samples at their ideal temperature.
  • Save Costs, Misinterpretation and Potential Disputes
    The Model Fx also reports the temperature at which the sample was measured. Should any disagreement occur between supplier and customer, this additional unique functionality can help dissolve any dispute, thereby saving time and costs. Currently, non-repetitive analysis across refineries is still an issue.
  • Ensures You Are Compliant to Standards
    The Model Fx measures according to the Lovibond® RYBN, Lovibond RY10:1, AOCS RY, Chlorophyll & b-Carotene scales which are most commonly used in the Edible Oil Industry. Being able to report according to these standards means that you are compliant to the internationally accepted methods.
  • Ideal for Continual Use in Edible Oil Refineries
    The Model Fx is housed in robust, chemically-resistant aluminium casing (100% recyclable and sustainable).
    The sealed unit and removable sample chamber are easy to clean of any accidental oil spillages to avoid any impact on accuracy.
