Description

The M550 is a high performance True Double beam spectrophotometer with parallel sample and reference beams. Two Silicon photodiodes are used for measuring the two beams simultaneously for optimising measurement ac- curacy and stability. The reference beam is especially useful for measuring samples where the refence changes with time. This specification is as expected from a top-of-the-range instrument designed for research as well as routine use.
