Product Information

The ATM-420 has been specially designed to meet the needs of the sugar processing industry. The color of refined beet or cane sugars is determined according to internationally accepted ICUMSA method 4 and a direct read-out is given in Milli-Absorbance Units (MAU's). A standard RS232 output is provided for recording results on a printer or PC.

Only the highest quality optical components have been specified in the design and construction of the ATM-420. These include a narrow bandwidth interference filter which can be fine tuned to ensure the greatest possible wavelength accuracy. The light source has its own lamp house for easy alignment and adjustment.

An optional cell holder accessory for shorter path-length sample cells is available. This is ideal for measuring raw or brown sugars.
