Remote airborne particle counter meets new ISO standards

Published: 21-Oct-2008

A US company has unveiled its latest range of remote airborne particle counters.


The MET ONW 7000 from Hach Ultra – a subsidiary of Danaher Corporation – in Grants Pass, Oregon, aims to meet requirements of the new ISO 21501 calibration standard.

Manufacturers using cleanrooms classified under ISO 14644 are recommended to use the new ISO for calibration of their optical air particle counters. The new ISO 21501 replaces the ASTM F328.

The MET ONE 7000 Series is also suited to meet the specific needs of cleanroom operations within the pharmaceutical, vaccine, medical implant and equipment manufacturing industries using aseptic and sterile processes.

It is available in a sensitivity range of 0.3 to 10 ?m, and flow rates of 2.83 LPM or 28.3 LPM and can be integrated into most facility monitoring systems, including RS485 Serial Modbus, Ethernet, Analog and Wireless.

These communication choices and an array of mechanical quick-connect installation hardware also reduce downtime related to instrument removal and re-installation during routine calibration and preventative maintenance work.

The MET ONE 7000 Series is tolerant to washdown and VHP-based disinfecting processes.
