With clean air, the pre/post-process suchas drying process is not necessary
Various kinds of parts/components canbe tested by just exchanging the capsulefixture.
For electrical components etc require
the test by Helium detector, combination
use of LZ-1550 allows no dead band test.
(Helium detector is not included)
Judgment lamp gives the easy visual test
result information
DPS resolution is 0.1Pa thanks to highperformance DPS and AD converter
Cosmo-developed Air operated valve
ensures the durable and stable test
Ideal for testing various kinds of parts /componeents.
Test data can be stored in PC via
RS-232C communication■ Functions
