MET ONE R4800/R4900 Remote Air Particle Counter

The MET ONE R4800 and R4900 series remote air particle counters are affordable, reliable and provide accurate data in particle monitoring systems. A compact design with flexible sizing, flow rate and communication options address the specific needs of cleanroom operations in pharmaceutical, semiconductor, hard disk drive and flat panel display industries.

• Easy to integrate with any facility monitoring system
• 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)
• 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.
