The compact handheld refractometer DR201-95 offers an extended measurement range of the refractive index and the sugar content of nD 1.3330–1.5318 and 0–95 % Brix. The automatic temperature compensation for the Brix scale helps the user with the measurements of beverages and sugary confectionary products. The device is splash-proof and meets the IP64 standard.

As an entry-level model for the digital refractometry, the DR101-60 covers the measurement ranges between nD 1.3330–1.4419 and 0–60 % Brix. Thanks to the automatic temperature compensation for the Brix scale, you can achieve reproducible measurement results even under changing environmental conditions. As a water-tight device, the DR101-60 meets IP65 code and can be cleaned under running water.

The AR4 determines the refractive index between nD 1.3000–1.7200 and the sugar content in the range of 0–95 %Brix of liquid, viscous as well as solid samples. Dry substance content in % and the dispersion value nF-nC can be calculated.

• Measurement of liquid, viscous and solid samples, regardless of their turbidity, viscosity, transparency and absorption
• Suitable for the measurement of foils and solids
• Large measuring range of nD 1.3000-1.7200 and 0-95%Brix, scale manually adjustable
• Reading the measured values via an eyepiece
• Robust housing and easy handling
• With thermostat connections that allow for the temperature control with an external thermostat

The smallest circulation thermostat on the market

The PT31 circulation thermostat is equipped with highperformance functions. The 1.5 kg lightweight device is ideally suited for applications requiring a temperature range at a constant level. The proven Peltier technology offers process-reliable temperature control in the range from 8 °C to 35 °C. The accuracy of temperature control is ±0.2 °C.

The robust locking mechanism of the PT31 provides a sturdy connection and ensures constant temperature control of the medium. The compact and sturdy design does not require much space and can be placed anywhere in the laboratory.

Temperature control range 8-35 °C- The electronic circulating thermostat with Peltier element is a versatile and powerful device for controlling the temperature of refractometers and polarimeters. It is extremely robust, compact and easy to use. Due to its small size, it requires little space in the laboratory.
