Hardware
Persium Node
The Persium Node gives industries, researchers, and compliance teams the high-resolution environmental data they need to capture what other sensors miss and respond with confidence.
✓ One reading every 15 seconds, 240 data points per hour
✓ Captures short-lived emission spikes conventional sensors miss
✓ Wind-aware data for real-time source apportionment
✓ Always-on cloud connectivity via 4G, LoRa, or WiFi
✓ Timestamped, audit-ready data for compliance and research

Built for the people who work in the environment, not just monitor it.
Built for the people who work in the environment, not just monitor it.
The Node View is built for the field, for technicians, site managers, and operators who need to read the environment on the spot, make a call, and move on. The screen is there because they need it to be.
Verify your installation before you leave the site.
Field technicians can confirm sensor performance, check data accuracy, and validate installation health directly on the device screen, without waiting for cloud data to sync or pulling out another device.
