Kofloc Model CR-400 Mass Flow Meter | Compact Readout Unit
The CR-400 readout unit, when connected to your mass flow controller or meter with a cable, provides the key mass flow functions, such as flow measurement and control as well as cumulative flow calculations and flow event outputs.
This readout unit offers RS-485 communications capability, so multiple readout units can be controlled online by a host computer. * The CR-400 is fully compatible in size with the CR-300.
