EComparator Range Color Graders

Gardner - ASTM D1544, D6166; Saybolt - ASTM D156, D6045; ASTM Color - ASTM D1500, D6045; Pt Co - ASTM D1209

The Lovibond® EComparator Series provides an easy way to transition from subjective visual measurement to a non-subjective, accurate electronic measurement.

Color graders who are used to the traditional comparator series sometimes find the upgrade or transition to an electronic system daunting. The assurance of relying on physical color difference is diminished.




  • Advance from Visual (subjective) to Electronic (objective) Color Measurement.
  • Immediate & Accurate - Straight from the Box.
  • Guaranteed Agreement with International Standards
  • Display Results with On-Screen Color and Numerical Options Digital, Portable, Push-Button Technology
With the EComparator Series, viewers can view the color difference:
  • On-Screen Color
  • On-Screen Numerical Display
The user friendly ergonomics and intuitive interface guarantee new users can be quickly trained and easily supported. Large data storage (> 20,000 readings), USB connectivity ensures readings can be stored and shared easily and quickly. Flexibility is further enhanced with software packages for Windows® with multiple language* support on-screen. Touch screen technology makes the EComparator Series easily programmable with instinctive menus on screen. Users can set language, date and time, view preferences and create projects with individual tolerance settings. An on-screen warning system of:
  • Within Tolerance = Green
  • Outside Tolerance = Red
  • On Border of Tolerance = Amber
  • Provides the user with immediate information on the sample.
  • Supported Languages: English, French, German, Spanish, Italian, Chinese, Japanese, Russian
Lovibond® accuracy and efficiency is apparent throughout. With robust casing and a small laboratory
footprint, the EComparator Series is the ideal solution for users wishing to experience the benefits of
immediate, accurate, electronic readings: the best of both worlds.

Often referred to as Pt-Co, Platinum-Cobalt, Hazen or APHA Color or TCU - all terms are interchangeable and equally valid.

Used to measure clear to dark amber liquids. Originally defined by specified dilutions: range from 0 at the light end of the scale to 500 at the darkest. Used extensively in the water industry but also for clear oils, chemicals and petrochemicals such as glycerine, plasticisers, solvents, carbon tetrachloride and petroleum spirits.

GARDNER COLOR (ASTM D 1544, ASTM D 6166, AOCS Td 1a, MS 817 Part 10)
Single number, one dimensional, color scale for grading the color of similarly colored liquids
The scale ranges from a pale yellow to a red in shade and is described in terms of the values 1-18. Used to measure color of resins, varnishes, lacquers, drying oils, fatty acids, lecithins, sunflower oil and linseed oil.

The Saybolt Color scale is used for grading light colored petroleum products
The color range of the Saybolt-scale is similar to that of the Platinum-Cobalt/Hazen/APHA Color (ASTM D 1209) scale and is therefore employed for the measurement of water-clear, colorless to slightly yellowish products.

The faintest coloration is Saybolt-color number +30, the strongest evaluable Saybolt coloration value is -16. Popular for aviation fuels, kerosene, naphthas, white mineral oils, hydrocarbon solvents and petroleum waxes.

ASTM COLOR (ASTM D 1500, ASTM D 6045, ISO 2049, IP196)
ASTM D1500 is a single number, one dimensional, color scale ranging from a pale straw through to a deep red in sixteen steps (0.5 - 8.0 units in increments of 0.5 units).

Please note the Chinese Industrial Standard SH/T 0168 (0 to 25) is directly related to ASTM D1500 (0 to 8.0). Sometimes referred to as the "mineral oil color value", the ASTM Color Scale is widely used for the grading of petroleum products such as lubricating oils, heating oils and diesel fuel oils.
