Application
These standards are designed for the calibration of instruments,
used for the measurement of adsorbed activity in charcoal
and aerosol filters.
Construction
An activated plastic layer 0.2mm thick, is located between
two paper labels 0.15mm thick and heat sealed between plastic
foils 0.125mm thick (drawing: VZ-1158). Please enquire for
larger diameters.
An activated plastic layer 0.3mm thick, 50mm in diameter is
mounted onto a backing plate and covered with a 0.3mm thick
aluminium foil. The backing plate is glued into a ring holder
60mm in diameter, 3mm thick (drawing: VZ-538). |
