This SCHMIDT+HAENSCH automatic microprocessor controlled critical angle refractometer is designed to measure refractive index of liquid media independent of opacity, viscosity and colour. Consisting of separate electronic and measuring devices, a sample volume of 0.3 ml dropped or poured into the Peltier-thermostable sapphire prism is sufficient for measurement. 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 separate electronic housing incorporates a splash-proof alphanumeric touch panel and a large LCD display. Batch numbers can be entered directly and simple forms can be created and printed out. The % Brix is temperature corrected within +10 to +50 °C. With a working temperature between +10 °C and +70 °C, the ATR-W2 is ideal many applications in the chemical, food, beverage, medical, pharmaceutical and petrochemical industries.

Equipped with extensive software and a thermostatable sapphire prism, the DUR is designed to measure the refractive index of liquid media independent of opacity, viscosity and colour. Constructed of stainless steel, the DUR-SW can be placed horizontally or vertically. A range of sample chamber seals, with or without water circulation, and the facility for manual or fully-automatic sample changing completes the versatility. The DUR models feature high accuracy measurements with sample identification, real time clock, up to 30 free programmable user specific scales and self-check for error detection. Data transfer to printer or PC is via a RS 232 C interface and additional interfaces are available. The DUR measuring head may be coupled to the POLARTRONIC M, H, and SACCHAROMAT models, reducing investment costs considerably. DUR-SW is ideal for applications in the chemical, food, beverage, medical, pharmaceutical and petrochemical industries.

IPR 3/2

Ideal for online use within process environments, the IPR 3/2 is a modular, automatic refractometer designed to measure continuously the refractive index of liquids. From this, the concentration of a binary or quasi-binary liquid mixture may be determined. IPR 3/2 is a modular system - the electronic controller (IPR2) being capable of working with up to three measuring heads (IPR3). A basic configuration is one sensor coupled with one electronic unit. The IPR2 controller has a freely configurable LCD display, a keypad for data input, menu selection and programming, and a n RS232 serial interface for data exchange. Highly flexible, the IPR3 head benefits from a large measurement range. The head is manufactured from stainless steel for chemical resistance making it suitable for foodstuffs and CIP and pipe pig use. It can be installed in pipes, reactor vessels, mixing tanks, kettles, boiling pans and evaporators, using different weld-in flanges. The measurement is independent of light intensity from the light emitting diode (LED) and is free of signal drift, granting high precision and better process control. The IPR 3/2 is unaffected by colour, turbidity, undissolved particles or gas bubbles.
