Welas and Promo 2000
Most Versatile

CH Technologies' Welas and Promo 2000 Series are the most versatile of the Welas and Promo families. Manufactured by Palas GmbH, these white light spectrometers feature the state-of-the-art particle counting technologies found in all of our spectrometers and are executed with the high quality standards for which Palas is known.

The 2000 series was designed to provide the most flexible system available. The 2000 Series sensor can be placed up to 50 meters away from the control unit with virtually no loss in measurement accuracy. This capability is made possible by Palas' proprietary lightwave cables. The integrated touch screen in the Promo units makes it ideal for a real time particle monitoring system for industrial or lab settings.
