Photometer The Thermo Scientific Orion AquaMate 7000 Vis Spectrophotometer is designed for water analysis and beyond with over 260 preprogrammed methods compatible with several leading brands of reagents plus user customizable methods for absorbance, % transmittance and concentration testing. Methods are stored on the included USB memory stick, so they can be added or removed from the instrument as needed. Methods can be adapted for new chemistries or operators can create their own custom methods. The AquaMate 7000 Vis offers 325 to 1100 nm selectable wavelengths and 5 nm spectral bandwidth and is ideal for most routine concentration measurements. For its relatively small footprint and lightweight design, it boasts numerous features at a competitive price. The intuitive user interface and simple single-beam optical geometry provide accurate, reproducible results. This product includes: Methods on a USB memory stick, the 3-position cell holder, user documentation, a dust cover, USB cable, and 110V and 220V power cords.
