8. Maintenance
®
PALAS
recommends an annual maintenance of the dilution systems. The maintenance
procedure includes besides of an entire function check (e.g. annular clearance, dilution
factor) the issueing of an updated calibration certificate. Additionally, the particle cleanliness
of the VKL is being checked and reconditioned in case of contamination.
Additional information: Does your dilution system has to be maintained
ahead of schedule?
Function test of the VKL series in the laboratory:
-
with the simple test set-up (see figure. 1), the dilution systems can be examined by
everyone
-
first, in measurement 1, the particle concentration of the room air is measured
-
afterwards, the test system is connected between VKL 100 and the OPC (see figure. 2)
and the measurement 2 is performed
-
the dilution factor can be determined according to formula 2
