ATR-W2, automatic microprocessor controlled critical angle refractometer

 

Automatic critical-angle refractometer This SCHMIDT+HAENSCH automatic microprocessor controlled critical angle refractometer is designed to measure refractive index of liquid media independent of opacity, viscosity and colour. It consists of separate electronic and measuring devices. A sample volume of 0.3 ml is sufficient for measuring. The sample is simply and easily placed by dropper or pouring onto the Peltier-thermostable sapphire prism. The prism is illuminated by long life yellow LED and the angle of total reflection is detected by diode array which guarantees high resolution and stability. The ATR-W2 enables to complete measurements in a quick and simple way by using splash proofed touch-in panel with four definable keys, - START ALPHA PRINT MENU and a large illuminated 2 lines, 20 characters graphic LCD. The % Brix is temperature corrected within +15 to +40C.
