Applications:
SCHMIDT + HAENSCH refractometers can be used for purity investigations, sample recognition, dilution control, or composition. They are also used for the characterization of substances or the determination of substance composition, especially of organic liquids or raw materials. With different sample chamber compartment doors, it is also possible to measure solid samples, making it suitable for other applications, such as quality control of optical films, glass, or fibers. Refractometers are also widely used in food, oil, fuel, and other industries to measure and monitor the concentration of components throughout the fabrication process.

SCHMIDT + HAENSCH proudly presents a robust, multi-wavelength refractometer that performs simple dispersion measurements at seven wavelengths over the visible range. The digital, fully automatic spectral refractometer ATR L is an electronic unit separated from the robust stainless steel measuring unit.

Checkpoints:
• Measurement of solid samples possible
• Automatic dispersion measurement
• Seven wavelengths fixed with a full range of visible light
• Automatic measurement of Abbe-number
• Ideal for research and development
• Able to discriminate ingredients with the same refractive index
• Powerful, internal Peltier temperature control guarantees the fastest measurements with the highest accuracy

Applications:
The SCHMIDT + HAENSCH multi-wavelength refractometer ATR L can be used to determine product purity. Hence, it is ideally suited to control sample quality. Moreover, the material characterization can identify high-quality products like perfumes, wine, or other alcoholic beverages. As the instrument can measure solid samples, the quality control of hydrophobic and hydrophilic intraocular lenses (IOL) is possible.
The measurement principle is also sensitive to absorption, delivering valuable information about the analyte's content and turbidity. Further applications in R&D, medical research, plastic lenses, contact lenses, proteins, communication technology, polymer materials, special optical liquids, glasses, and glues are possible. ATR L can provide valuable services to the petrochemical industry, scientific research, and standard ASTM measurement.

The robust ATR P critical angle refractometer is specially designed for use in the sugar industry and for determining mixing ratios or mass fractions. The system consists of a firm and waterproof stainless steel ATR P measuring head and the VariControl unit, which has a high-resolution 7″ TFT Touchscreen.

Checkpoints:
• For permanent use in production laboratories
• High performance and accuracy even in a rugged environment
• Easy handling of the sample compartment
• Measurement of sedimentary samples possible
• Easy calibration
• GLP/GMP
• LIMS integration
• Data storage space for over a thousand products, each including all measuring methods
• 21 CFR Part 11 conformity

Applications:
SCHMIDT + HAENSCH ’s ATR P applications have food and beverage, sugar, petrochemical, and refinery applications. It can measure liquid samples containing solid matter with high precision, making it applicable to the quality control of liquids like fruit juice.
Specially designed for use in harsh environments.

This digital handheld refractometer DHR by SCHMIDT + HAENSCH allows for rapid, on-site measurements of high or low-viscosity liquid substances.
The full view of the LCD screen of the DHR displays reliable results with high precision (five digits) in 2 seconds. SCHMIDT + HAENSCH’s DHR can be used in agriculture, e.g., to determine the point of harvest, or in the automotive industry, e.g., to analyze antifreeze.

Checkpoints:
• Ideal refractometer for fast, on-site analysis
• Specific scales for many applications
• 5-digit LCD
• Measurement results in fewer than 2s

Applications:
Handheld refractometers are primarily used in agriculture for point-of-harvest determination and in the food and beverage industry.
DHR models are available with two refractometer scales, which can be used to analyze materials such as honey, wine, saline, glycol, and antifreeze.

The SCHMIDT + HAENSCH ATR BR is a stand-alone critical-angle refractometer for measuring liquid media from low to high viscosity, independent of opacity and color. Thanks to a wide variety of configurations, it is adaptable to different production and laboratory applications and offers an excellent price-performance ratio.

Checkpoints:
• Robust refractometer
• Stand-alone device
• Stable, precise measurements
• Versatile applications
• Easy handling, user-friendly operation
• Excellent price-performance ratio
• Flat and small sample chamber for easy cleaning

Applications:
ATR BR can be used in the chemical industry to analyze a range of compounds, such as solvents, organic polymers, distilled products, or solutions for inorganic compounds. The ATR BR can be applied to analyze yogurt, jam, fruit extract, syrup, honey, coffee extract, vegetable fat, albumen, chocolate, milk, and baby foods in the food and beverage industry. The quality of soft drinks, fruit juice, wine, and beer can be controlled. Medical applications include analysis of serums, blood, and urine. In the petrochemical industry, ATR BR can be used to monitor, e.g., oils, fats, waxes, naphthalenes, raw oils, varnishes, and paints.
