Bench-top control centre is capable of monitoring up to eight independent inline optical sensors. The sensors employ technology that interprets changes in refractive index to provide real-time process monitoring. The new data monitoring unit provides a built-in touch-screen interface and reduces footprint by over 50%. Due to a new ergonomic form and smaller size, the unit is suited for use in a range of environments, from a small process development laboratory up to industrial scale requirements. The multichannel capabilities of the device allow it to be connected to a number of sensors, whether in a single, multi-stage process or in situations where multiple processes are running in parallel.
