The IsoAir Pro-Plus Remote Particle Counter from Particle Measuring Systems (PMS) incorporates multiple cleanroom monitoring technologies into one instrument to customize cleanroom monitoring. With a small footprint, this particle counter is designed to give the user flexible installation options for power, WiFi, and analog and digital I/O capabilities. The external is stainless steel and liquid resistant to protect the unit during cleaning activities and harsh environments. Particulate contamination is measured through up to 8 channels from 0.3 to 25 micrometers. The integrated HEPA filtered blower reduces the need for extraneous external connections and supporting equipment. With plug-and-play connectivity, the user can integrate this product into PMS or third-party facility monitoring and compliant data management software systems. Additionally, the quick release mounting bracket stores essential sensor data, reducing the time and complexity of unit installation after calibration or servicing.
