Zephyr ESR 2


The Zephyr ESR 2 is the latest rapid particle characterization instrument from Occhio. Using a large upper funnel and a weight sensing, auto-correcting, vibrating dispersion unit, the ESR 2 makes quick work of large volume samples. Using one of the fasted cameras available, capable of over 75 images per second, the sample images are captured as the particles fall between the camera and the backlight into the recovery bin. Created to replace, with perfect correlation, traditional sieve methods, this instrument comes with TWO software programs, the traditional Callisto 3D and Granusize, an innovative, easy-to-use software which uses preprogrammed “buttons” to analyze samples with little to no personnel training.
