| Meets DIN 67 530, ISO 2813, ISO 7668, TAPPI T 480, & ASTM D 523 |
Dr. Lange has developed new reflectometers which produce fail-safe measurement and gloss-rating results in accordance with DIN 67530, ISO 2813 , ISO 7668, ASTM D 523, and TAPPI T 480. The reflectometers value should remain within certain limits for the measurement. In general, the viewing geometry of 60° is employed. If the reflectometer values exceed 70 then measurements should be made pursuant to the standard for 20°. The 85° geometry is used for 60°values below 10 (ASTM D 523).
Refo 3D & Refo 60D have an extended measuring range for measuring mirror reflection for metal surfaces in accordance with ISO 7668. This optional mirror standard (GL-1639) has a polished aluminum surface with a transparent quartz coat as protection against corrosion. The metal mirror standard is calibrated against a quartz wedge specified in ISO 7668 at BAM (Federal Institute of Materials Research and Testing) in Berlin, Germany.

| Refo® 60D - Fundamental Gloss |
For accurate routine checks.
Begin objective gloss measurements with REFO® 60, used for accurate gloss measurement during production, i.e. measuring, deciding and correcting while production is in full swing. At the touch of a button the result appears immediately on the display and REFO® 60D stores it for later evaluations. This handy reflectometer goes with you to all places of production.

With the 60°geometry for a wide range of application.
The 60° measuring geometry is the best one for standard gloss measurement from the physical and optical points of view. The measuring accuracy in the extreme high-gloss and matte ranges is satisfactory for routine purposes. Additionally, REFO® 60D measures metallic surfaces using the optional metal mirror standard (GL-1634). |
| Refo® 3D - The Gloss Professionals |
 |
For best flexibility and measuring accuracy.
REFO® 3D is an easy-handling portable reflectometer with a three-angle geometry which is perfectly suited to each and every field of gloss measurement. Whether in the lower range of matte surfaces (85° angle), in the mid (60°) or high-gloss range (20°), it always provides precise and guaranteed results. Before measuring metal surfaces, REFO® 3D is calibrated against the optional metal mirror standard (GL-1639) specified in ISO 7668 |
Three modes of operation are at choice:
|
- One-angle measurement as single or multi-measurement stating also mean
value, standard deviation and coefficient of variation.
- Three-angle measurement as single or multi-measurement stating also mean
value, standard deviation and coefficient of variation.
- Gloss difference measurement against a reference variation.
|
| |
One-button easy operation. Before starting to measure, touch the button to calibrate REFO® 3D to standard within a few seconds. Then measure, read-off, print and evaluate the result.
Measurement memory Refo® 3D. For local measurements REFO® 3D features a data logger to keep all information available for further analysis.
Continual Gloss Measurement. Measurements are made automatically in 3 sec. intervals. |
