ATR-P Touch
Refractometer

TheATR-P is a critical angle refractometer specially designed for applications in the sugar industry. The complete system consists of the ATR-P measuring head and the “L-Controller” electronic unit or the ATR-P measuring head can be connected to a PC or laptop. The user-friendly “Aquisys Basic” PC software is included with the basic configuration.

  • 21 CFR part 11 conformity

Like all devices from SCHMIDT + HAENSCH, this refractometer is easy to use and delivers highly accurate and reproducible measurement results. Depending on the application, the ATR-P enables both individual and flow measurement. The measuring head can be placed both vertically and horizontally to the sample space. Since the measuring head can be used in both a horizontal and a vertical position, liquid samples with solids can also be measured, making the ATR-P ideal for quality control of liquids such as fruit juice. Calibration can easily be done with a sucrose solution. The measuring head of the ATR-P can be connected to a PC or laptop. Documentation according to GLP / GMP is part of the proven Schmidt + Haensch quality. In addition, the integrated Aquisys 2 software guarantees compliance with 21 CFR part 11.
