Particle Counters

Compiled by Carrie Meadows

Particle monitoring is an integral part of maintaining adequate cleanliness levels. Here’s a selection of the latest particle counting equipment available.

100 LPM airborne particle counter

The Biotest APC M3 was the first portable airborne particle counter to sample at a rate of 100 LPM. Measuring 1 m3 of air in only 10 minutes, it cuts the time of particulate air monitoring for its users. When sampling a cubic meter of air, conventional 1.0 cfm (28.3 LPM) units take more than 35 minutes; 50 LPM units take 20 minutes. The APC M3’s higher flow rate reduces the time required to take samples by as much as 70 percent, thereby helping pharmaceutical manufacturers increase productivity and lower labor costs. The counter can also be used with Biotest’s APCOne11–21 CFR Part 11 compliant–Download Utility Software. The software securely transfers data to reduce operator error and meets FDA compliance for data protection. It also has an audit trail to log critical events, password protection features, and digital signature application for authentication of files.

CLiMET offers 100 LPM sampling with the CI-1053. The airborne particle counter completes a full cubic meter sample in 10 minutes, achieved with a filtered external exhaust that significantly reduces particle emissions. The CI-1053 also incorporates communications capabilities via Ethernet Modbus, TCP/IP, and TELNET. The 14.25-lb particle counter is housed in a seamless stainless steel enclosure, with an internal battery that provides four hours of continuous sampling. The bright touchscreen provides a user-friendly interface. The standard two-year warranty underscores the design, performance, and quality of the CI-1053. This new family of particle counters is also available in similar products with flow rates of 1 cfm, 50 LPM, and 75 LPM.

Hach Ultra’s latest MET ONE 6000 Series of remote airborne particle counters features the MET ONE 6015, offering accurate, reliable, continuous particle monitoring for the life science industry. Providing a sensitivity range of 0.5 to 10 µm at 1.0 cfm flow rate, the 6015 is designed to meet the specific needs of cleanroom operations with diagnostic features that provide reduced troubleshooting and downtime related costs. Featuring a wide choice of communication options such as RS-485 Serial Modbus, Ethernet, analog, pulse, and RS-232, the counter is easy to integrate with any facility monitoring system and enables future upgrading as communication needs change. An array of mechanical installation options also reduces downtime related to instrument removal and re-installation during routine calibration and preventative maintenance work. For the life science industry, the device installed with Hach Ultra recommended FMS software such as UVO or enVigil meets the necessary regulatory compliance needs for 21 CFR Part 11. The particle counter can also be integrated with the most commonly used industrial building management system and SCADA software with an OPC server.
