View resource →Product overview
The Lovibond® Model F is a benchtop visual colorimeter using calibrated Lovibond RYBN glass colour standards. Under controlled illumination approximating daylight, the viewing tube presents adjacent sample and comparison fields. Red, yellow, blue and neutral filter racks are moved until a visual match is obtained and the result is expressed in Lovibond units.
Key features
- Eleven durable racks contain calibrated Lovibond red, yellow, blue and neutral glass standards.
- A prismatic optical system provides two adjacent, balanced fields for direct comparison.
- An integrated blue filter and illumination approximating daylight help standardise viewing conditions.
- Path lengths up to 153 mm (6 inches) support transparent and translucent samples; opaque solids, powders and pastes can be assessed with the appropriate optional solid-sample accessory.
- The white sample-chamber liner is removable for cleaning or replacement, and individual glass filters can be serviced separately.
- Specified by multiple oil, fat and food colour methods for laboratory and production quality control.
