Easy in Use
The VariRef combines proven SCHMIDT + HAENSCH technology with the modularity of the VariFamily. The new double isolated peltier systems allows fast temperature control and reduces the influence of environment temperature, resulting in rapid and precise measurements. The VariRef has the well-established SCHMIDT + HAENSCH sample chamber. Its flat shape is ideal for easy cleaning. Different sample chamber covers for liquids and solid samples makes it possible to adapt the device to your application. When dealing with hard-to-clean or hazardous materials we offer a special covered version to ensure a long and reliable product lifespan.
SCHMIDT + HAENSCH refractometers can be used for purity investigations, sample recognition, dilution control or composition. They are also used for characterization of substances or for 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 which makes it also 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.
Product in depth
The new user-friendly Aquisys 3 software can be accessed either using a 7” user interface or remote via Google Chrome on your favorite device, smartphone, tablet or personal computer. As part of the VariFamily the VariRef can be used from different users simultaneously, enabling lab managers to handle and sign data, while lab technicians are still measuring.
Modules of the Vari Ref are:
VariRef A: high standard, high resolution and repeatability; mainly for research and development and special pharmaceutical applications
VariRef B: different measurement ranges depending on application, highest range of temperature, for all different industries (depending on measurement range)
VariRef C: basic model, most economic version, high temperature range, for all simple applications such as use in the food industry production labs.
