Topas: Measuring instruments

This optical method counts and sorts particles independently, one by one, according to their size, without any a priori asumptions. It is very fast, offer excellent sensitivity and accuracy. One other advantage is that relation between the optical effect and size is straightforward and intertrepation is easy. Alongside we offer a loarge range of accessoiries and software for one by one counting, measurement of concentration with very high resolution and high sensitivity in a very large range of concentration.

The EMS electromagnetic vibrator has been specially designed for use with microsieves dia.75 mm. Vibration amplitude can be adjusted manually to match any powder condition and provide excellent reproductibility. It can be used for microsieving, angle of repose measurement, vibration of small objects (powder column, dosing funnel). Specification Clamp for sieves 75 mn, Frequency 100/120 Hz (on 50/60 power). Amplitude : Max.1 mm ; amplitude range : 10 %...100 % ; 230 VAC 50/60 Hz (operation at 110 V requires step up transformer) ; 70 x 140 x 270 mm (Tripod : dia.15 mm, 480 x 200 x 320 mm) ; weight : 3.1 kg (Tripod : 3.7 kg). CE Marked.
