ULTRATEST UL 500
Stationary Helium Leak Detector
The ULTRATEST UL 500 is an automatic leak detector offering
fast pumpdown and short response times.
Advantages
◆ Wide dynamic measurement range over 14 decades
◆ Leak detection is possible from atmospheric pressure
◆ Short pumpdown and response times
◆ Fully automatic run-up and very simple to operate via two
main push-buttons
◆ Large, clearly arranged and easy to read LCD display with analog
and digital leak rate readout, and status display with alphanumeric
plain text display for user guidance
◆ Autoranging Ð rapid automatic range switching
◆ Autozero Ð automatic Zero alignment
◆ Autocal Ð automatic calibration via built-in calibrated leak
◆ Low-maintenance special turbomolecular pump for quick operational
readiness and high pumping speed at the test port
Typical Applications
Quality control of all types of components, continuous short cycle operation
of large quantities (series testing) and single tests, for example in:
◆ Electrical industry
◆ Semiconductor industry
◆ Cooling and air conditioning industry
◆ Automotive industry
◆ Container assembly
◆ Packaging industry
◆ Precision mechanics
◆ Research
The UL 500 can be used in connection with a helium sniffer for
overpressure leak detection.
◆ Electro-pneumatically operated long-life bellows-sealed valves
◆ Mobile unit (table top enclosure) on castors
◆ Optional V.24 / RS 232 C computer interface
