Product Features
Casella prides itself on providing precision instrumentation since 1799, supplying eminent figures including Darwin and Livingstone. A lot has changed in our 200-year history, but what does remain is our commitment to reliable, trustworthy and credible solutions.
The Casella Guardian 2 Area/Boundary Monitor is an advanced area and boundary monitoring system designed to help organisations comply with environmental regulations. It offers real-time data collection and remote access, making it ideal for construction sites, industrial facilities, and any location where monitoring environmental impact is critical.
With the Casella Guardian 2 Area/Boundary Monitors, users can track multiple parameters such as noise, dust (PM10, PM2.5), wind speed, wind direction, and VOCs (volatile organic compounds) — all in one robust, portable device.
