ATR W Series

Description

Refractometer ATR W series

Laboratory refractometer with integrated Peltier-Thermostat, working temperature up to 80°C.

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-W1 enables to complete measurements in a quick and simple way by using splash proofed touch-in panel. It's new housing for the electronic offers more space for a bigger LCD display and an alphanumeric foil keypad. Batch numbers can be entered directly and also simple forms can be created and printed out. The %Brix is temperature corrected within +10 to +50 °C.

In the ATR W series are four difference models, they have other parameter for the measuring ranges, the resolution and the precision. Please see table "Technical details".

NEW: Serial to Ethernet converter for data transfer to PC
