DC 10000

DC 10000 dilution cascade with electrical operating pump

•    No compressed air connection; only electrical power supply 115 - 230 V, 50 - 60 Hz
•    Dilution factors 1:10, 1:100, 1:1,000, 1:10,000
•    The user can perform a simple functional test on-site
•    The dilution systems can be combined with all common particle counters
•    The dilution systems from Palas® are characterized unambiguously. This is documented with a calibration certificate for each individual device.

Description

The DC 10000 consists of four cascaded special dilution systems with the dilution factor 1:10. The DC 10000 dilution cascade has one aerosol inlet and four aerosol outlets. Depending on which aerosol outlet is connected to the measuring device, the aerosol with the dilution factors 1:10, 1:100, 1:1,000 or 1:10,000 are diluted and measured.

The DC 10000 can be operated with all common optical particle counters (OPC) according to ISO 12501-4 or optical aerosol spectrometers (OAS) according to ISO 12501-1. The DC 10000 can be used up to a particle size of approx. 5 µm.

Functional principle

Fig. 2: Functional principle

Particle-free air with the volume flow VR circulates through an annular passage around the suction nozzle. Thus, according to Bernoulli, a volume flow VAn is generated in the suction nozzle.

The dilution factor VF is calculated according to the formula:

The DC 10000 needs no compressed air connection. So only an electrical power supply is necessary for operation.
