- MET ONE R4900 series remote air particle counters use industry standard 4-20mA interface
- Stainless steel enclosure compatible with most process environments
- Compact size for easy mounting with a vacuum source, DC power & communication line
Data Management
- MET ONE R4800 & R4900 counters respond to simple ASCII command instructions, including start, stop and report counts, send location number, etc.
- Reporting data includes counter status & particle counts in two size ranges
- Multiple display options via continuous monitoring feature (Particle Vision® Online & CIMScan® software
Operation
- User-programmed alarm level detects high counts on first channel triggering an alarm
- Auto alarm reset at start of the next count cycle
- Long-life laser technology for superior performance & extended service life
- No fan allows proximate placement to sensitive processing areas
Flexible
- Sensitivity ranges of 0.5um & flow rates of 1.0 cfm
- Onboard status indicator sets signal at connector for alarm Stay resident RS-485 configuration programming (count/hold times, alarm level/delay & scaling) maintained through power cycles
- Sensor resistant to vaporous hydrogen peroxide (VHP)
