| This is a portable, real time monitor for assessing the concentration of suspended particulate matter |
This is a portable, real time monitor for assessing the concentration of suspended particulate matter from 1mgm-3 to 2500 mgm-3. It is the only hand-held real-time dust monitor on the market with an integral real time, graphical display of dust concentration variations (no PC required). Each unit is factory calibrated, using a gravimetric technique. The instrument can be returned to this "factory" calibration setting at any time during its life by the use of a non-degradable calibration insert (supplied with every unit). An individual gravimetric calibration involves the simultaneous collection of a gravimetric (filtered) sample of the dust. In this way, two averages are collected over the exposure period. One is from the filter, while the other is provided by the averaging function within the instrument. It is then possible to derive the difference in these two figures and correct accordingly.
The unit features an internal logger that can store up to 15,700 data points over 32 separate runs. The logging interval can be set from 2 seconds to 10 minutes. At 2 seconds, it is possible to record 8.75 hours of data; at 5 minutes, this equates to a total logging time of 50 days. Recorded values include: Average concentration over the logging period (mgm-3), Maximum concentration over the logging period (mgm-3), Date and time stamp. Logged results are downloaded to the included MS Windows software package. |
