1. Description
• The Lindab leakage tester is designed to verify the
airtightness of duct systems, but can also be used
to test other enclosures (air conditioning units, cli-
mate chambers, electrical cabinets, furnaces, etc )
• The device measures the ow rate that is necessary
in order to maintain the selected test pressure in an
enclosed system
• The device uses a membrane keypad and an OLED
colour display to operate a menu-drive interface
• The test results can be sent to a local thermal printer
(included) via a wireless infrared interface
• The device can permanently store data, de ne cus-
tomers and measuring points, and transfer data to a
computer via a USB interface

value, whichever is greater
• Multilingual user interface (German, English, French,
Swedish)
• The device directly displays the current ow rate
without the need for analysis
• The airtightness is evaluated on the basis of the
airtightness classes de ned in DIN EN 13779 (identi-
cal to DIN EN 12237, 1507, 15727) The table below
shows the corresponding classes in other (older)
standards
• The Lindab leakage tester can be used to measure
positive and negative pressure – simply change the
Ø50 mm hose connector and select the relevant test
pressure
• The LT 600 is not approved for continuous use for
long periods in an attempt to locate leakages
