Spectrophotometer

Advantages

• Combi-device with two geometries according to DIN5033: 45°/0° and d/8°
• Small, flexible external probe head –  therefore ideally suited for measuring small and curved parts
• Wide range of accessories for measuring liquids, powders, granules, foods, cables
• High powered LED-light source with an optimal life span
• Perfectly simple handling through intuitive user interface
• Memory space for 1000 standards

 

Description

The sph870 is a user-friendly, portable spectrophotometer with a 45°/0° geometry, which due to the wide range of accessories available is suitable for a variety of surfaces and materials. For example, the system can be easily changed from the 45°/0° to a d/8° geometry simply by using our MA35 probe head adapter. The high-resolution technology enables a spectral scan in 3.5 nm steps in just 0.5 seconds. The menu is simple and well arranged, so that even untrained staff can perform the measurement task fast and accurate.
