ES-642 Cloud Lite
The ES-642 Cloud Lite brings together the Met One ES-642 MCERTS dust system with Svantek’s leading Class 1 sound level meter, the SV 307A. The ES-642 Cloud Lite is plugged directly into the SV 307A with data from both systems being uploaded live to our cloud platform, SvanNET, providing you with full PM10 and noise data sets.

Request a QuoteContact usThe ES-642 Cloud Lite system offers:
- PM10 or PM2.5 averaged and instantaneous results
- Configurable logger steps
- Advanced alarms for dust data alongside noise and vibration alarms
- Controlled input heater
- Lifetime warranty on microphone
- Inbuilt acoustic calibrator
- Automatic advanced alarms
Our dust system, has the advantage of only needing to be calibrated every 2 years, bringing the dust calibration interval in line with noise and vibration systems. This keeps your calibrations aligned and reduces the total cost of ownership, making it much lower than other solutions available.
Applications:
- Construction
- Infrastructure
- Demolition
- Military Applications
- Environmental Clean Up Sites
- Air Pollution Level Monitoring
