Atmospheric precipitation is collected in containers using a Bergerhoff dust measuring device. The collected sample is then evaporated, and the evaporation residue is determined gravimetrically. The sampling device consists of:
- 1 collecting vessel and
- 1 stand with protective basket.
- 1 wide-neck bottle with accessories
The collection container is a standard-production, wide-mouth, round HDPE container (DIN 120) with a capacity of 1.5 l. The container sits in a standard-production wire basket, which acts as a bird deterrent thanks to a funnel-shaped extension at the top.
The basket of the measuring device has a Rilasan coating to prevent heavy metal contamination resulting from the material of the basket.
Material:
The standard device is made of hot-dip galvanized or rilasan-coated steel. The stainless steel version of the Bergerhoff dust measuring device is made entirely of alloy 14571.
The main features of the Bergerhoff dust measuring device are:
- Low maintenance
- Determination of the dust content of precipitation (moisture disposition)
- good value for money
- quantitative collection
- Rilasan coating to prevent heavy metal contamination
- Stainless steel version is resistant to aggressive environmental influences, such as salts
