BAM-1022 Beta Attenuation Mass Monitor
Features:
- PM in-situ measurements with low measurement artefacts and good accuracy.
- Decreased frequency of background determination.
- Unmatched performance when operating at high ambient dew points.
- Remote operation and cloud-based communication are made possible by advanced communications features.
- Sophisticated diagnostics.
- Sensitivity is increased in comparison to previous in-line beta attenuation mass monitors.
- Weather data as well as data from other sensors.
