MODEL 1159-100
STAND-ALONE DILUTOR
Dilute without the need for compressed air
The 1159-100 is a diluter with a fix dilution ratio for a defined sample flow rate. It can be easily connected to any portable GRIMM aerosol spectrometer. The aerosol flow is split by a precision capillary into a sample and bypass flow. In the bypass flow all particles are removed by the built-in high-efficiency HEPA filter capsule. Downstream, both flows are mixed again. The actual dilution ratio is monitored by measuring the differential pressure over the capillary. No compressed air is needed.
