ATR-BR
Compact Refractometer
The ATR-BR is an automatic critical angle refractometer for measuring liquid media of various viscosities, regardless of color or transparency. The ATR-BR instrument is available in a variety of configurations for laboratory and production quality control.
The new housing allows more space for a larger LCD display and a splash-proof keyboard. Batch numbers can be entered directly and simple forms can be created and printed out.
Four special scales, one of which is a BRIX scale programmed at the factory, allow for a variety of uses in production and the laboratory. The ATR-BR software determines the mean and standard deviation of multiple samples. All functions may also be controlled via PC using the remote control program.
