Sensitivity range: 0.5 - 5.0 µm

Simplifies air particle monitoring for remote locations.

The IsoAir® 310P Air Particle Sensor makes it easy to monitor air in remote locations or in areas with process restraints.

Real-time particle monitoring gives quick notification of particle anomalies, detecting 0.5 and 5.0 µm for GMP and FDA compliance. A central vacuum is not needed to operate the particle sensor, and it features a built in “low noise” blower together with a Hepa filtered exhaust.

It has unparalleled performance in a chemical-resistant and easy-to-disinfect 316L box, and the passivated stainless steel surface has well defined microbial control characteristics.

The clean, reliable internal pump lowers installation costs and the need for costly vacuum system connections; the instrument is available with a wide range of communications protocol such as Ethernet, Modbus, Wifi, Analog 4-20mA for full compatibility with the existing monitoring system.
