Features of MET ONE R4800/R4900

Easy to integrate with any facility monitoring system  MET ONE R4800 series remote air particle counters use standard RS-485 serial communications MET ONE R4900 series remote air particle counters use industry standard 4-20mA interface. 

Flexible for all your remote air particle counter applications  Sensitivity ranges from 0.3um to 0.5um and flow rates ranging from 0.1cfm to 1.0cfm Onboard LED status indicator that flashes and sets a signal at the connector for alarm Stay resident RS-485 configuration programming (count time, hold time, alarm level, alarm delay and scaling) is maintained through power cycles (power on/off). 

Easy installation options  The small stainless steel enclosure is compatible with most process environments. There is no fan to disturb airflows, allowing the MET ONE R4800/R4900 series counters to be placed close to sensitive process areas.
