VHP Resistant Remote Particle Counters


A widely used method to inactivate bio-contamination on surfaces in GMP controlled areas is sporicidal gassing using vaporized hydrogen peroxide (VHP). This decontamination process uses a free radical reaction to kill microorganisms on surfaces.

The TSI family of VHP-resistant AeroTrak® Remote Particle Counters is ideal for GMP manufacturing applications where accidental VHP exposure can occur. Integration is easy using Ethernet (TCP/IP) and serial Modbus RTU communications. The instrument can be powered over its Ethernet connection (Power-over-Ethernet) to simplify installation, or via a local power supply. Configuration can be done locally with a PC or via a web browser.
