The ATR-ST Series Automatic Refractometers from Schmidt+Haensch offer the core features of the higher-end ATR-Series instruments, but at an economy budget level. The price performance ratio of these refractometers is exceptional. The small footprint of the single instrument design will easily fit in any laboratory.

All models feature a removable Teflon® prism well insert. This feature is exceptionally useful for applications involving the measurement of organic solvents and other caustic solutions, which are extremely harmful to the prism sealant for all other types of refractometers.

ATR-ST Series models come standard with automatic temperature compensation, long-lasting LED light sources (100,000 hours), linear high-resolution CCD sensors, menu-driven backlit LCD displays, 4 user profiles, password protection, printer and data ports, & optional USB ports.

The included software package and RS-232C cable make it very easy to connect the ATR-ST Series models to computers for collection of measurement data or for remote operation with full command of all functions. As new software versions are released, the instruments can also receive flash updates.

Schmidt +Haensch has been manufacturing precision opto-electronic instruments since 1864. All S+H instruments are manufactured in Germany.
