Grimm 11-D Advanced Real-Time Portable Dust Monitor
The Grimm 11-D is arguably the most advanced portable real-time dust monitor on the market today. Costing little more than other multi size fraction measuring instruments on the market, the German made 11-D is capable of ultra high resolution particle size AND particle mass measurements FAR beyond the capability of other dust monitors.
Measuring up to 100mg/m3, it can be used for a wide variety of indoor and outdoor air quality monitoring applications, including filter testing, aerosol research, workplace occupational health & safety monitoring, process analysis and much more.
It measures up to 75 different values in one compact portable device. These include:
- 31 size channels for particle number distribution
- 31 size channels for particle mass distribution (new)
- TSP – Environmental algorithm
- PM10 – Environmental algorithm
- PM4 – Environmental algorithm
- PM2.5 – Environmental algorithm
- PM1 – Environmental algorithm
- PM10 – Indoor air quality algorithm
- PM2.5 – Indoor air quality algorithm
- PM1 – Indoor air quality algorithm
- Inhalable fraction
- Thoracic fraction
- Respirable fraction
- Temperature at the measurement cell
- Humidity at the measurement cell
Some of the other features include:
- Integrated 47 mm PTFE filter (Grimm dual technology)
- Bluetooth, USB, Ethernet and RS-232 communications
- Sheath air system for protecting the laser and the detector in the optical cell
- Internal sensor for temperature (T) and relative humidity (RH) in optical cell
- 1.2 liter per minute flow rate
- Self-test of all optical and pneumatic components for the highest quality measurements
