FB series

The RKC Instrument FB series is an advanced series of temperature / process controllers with a very fast measurement frequency of only 0.05 seconds, which results in 20 PID calculations per second. This enables a very tight and accurate control of difficult to control processes.  The FB has recipe storage for eight settings and intercontroller communication for cascaded and master-slave functions.

De FB series comes in three sizes:
– FB100
– FB400
– FB900

– Leaflet FB100 series
– Leaflet FB400/900 series
