Purafil OnGuard 4000
The OnGuard 4000 is an active corrosion monitor atmospheric corrosion sensor designed to measure corrosivity in the air around sensitive electronics or control rooms.
• It uses copper and silver sensors (via quartz crystal microbalance technology) to detect corrosion film buildup (in Angstroms) due to corrosive gases (e.g. sulfur, chlorine, etc.).
• It also tracks temperature and relative humidity, since those influence corrosion rates.
• It logs data internally (with timestamps), so you can review trends or peaks, and supports remote access (e.g. via Ethernet network).
