These refractometers, which use the total reflection method, are handheld instruments for measurements in the laboratory and production environments. The backlit LC display and the simple intuitive menu structure allow the user to easily change settings in seconds. The sample can either be placed on the measurement cell or the sensor can be immersed directly into the fluid.

• Selectable automatic temperature compensation (ATC)
