The Unico S1205 Visible Spectrophotometer is an advanced, fully programmable, all-digital instrument designed for high accuracy and versatility. It builds upon the capabilities of the analog S1200 model and features a push-button, digital keypad wavelength change. Ideal for a wide range of laboratory applications, such as water testing, environmental analysis, and petroleum industry testing, the S1205 offers a large sample compartment that can accommodate cuvettes up to 50 mm path length.
With its high-quality silicon photodiode detector and 1200 lines/mm grating, the S1205 ensures excellent performance. It comes complete with a 4-position cell holder, USB port, RS-232 port, and a dust cover. The S1205 is CE approved and features optional Windows-based software for advanced data collection, wavelength scanning, and test method management.
