The robust ATR P critical angle refractometer is especially designed for applications in the sugar industry and for the determination of mixing ratios or mass fraction. The system consists of the robust and waterproof ATR P measuring head made from stainless steel and the VariControl unit with a high resolution 7″ TFT Touchscreen.
Like all SCHMIDT + HAENSCH instruments, this refractometer is easy in handling while providing highly accurate and reproducible measuring results. Depending on its application, ATR P allows for both single and flow-through measurement. The measuring head can be placed both vertically and horizontally with respect to the sample chamber. As the measuring head can either be used in a horizontal or vertical position, liquid samples containing solid matter can be measured, making the ATR P well-suited for quality control of liquids such as fruit juice.
Calibration can be performed easily using a sucrose solution. The ATR P measuring head can be easily connected to a PC or laptop. As always, the proven SCHMIDT + HAENSCH quality includes documentation according to GLP/GMP. Furthermore, the integrated Aquisys 2 software guarantees 21 CFR Part 11 compliance.
The applications of SCHMIDT + HAENSCH ’s ATR P span food and beverage, sugar, petrochemical, and refinery. Liquid samples containing solid matter can be measured with high precision making the ATR P applicable to quality control of liquids like fruit juice.
Especially designed for use in harsh environments.
The high-performance robust ATR P critical angle refractometer is designed for applications in the sugar industry, especially for the determination of mixing ratios (mass percent). The complete system consists of the robust and waterproof ATR P measuring head made from stainless steel and VariControl unit with a high resolution 7″ TFT Touchscreen. Due to the user friendliness and the easy handling highly accurate and reproducible measuring results can be rapidly generated. Various sample chamber covers allow single or flow-through measurement. As the measuring head can either be used in a horizontal or vertical position relative to sample, sedimenting samples can also be measured with high precision making the ATR P applicable to quality control of liquids like fruit juice. Easy calibration can be performed with a sucrose solution. As an alternative to the VariControl unit, the ATR P measuring head can be connected to a PC or laptop. As always, the proven SCHMIDT + HAENSCH quality includes documentation according to GLP/GMP. Furthermore, the integrated Aquisys 2 software guarantees 21 CFR Part 11 conformity.
