Description; Technical Data - Lindab LTEST LT 600 Mode D'emploi

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 flow 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, define cus-
tomers and measuring points, and transfer data to a
computer via a USB interface .

2. Technical data

Test values:
• Pressure measurement:
Principle: Piezoresistive semiconductor sensor
Measuring range: ±7000 Pa
Resolution: 0 . 1 Pa to ±900 Pa, then 1 Pa
Accuracy: ± 0 .5 Pa or ± 2 .5 % of the test value,
whichever is greater

Principle: Hot film anemometer
Measuring range: 0 .0000 to 55 .00 l/s (230 V, 50 Hz)
0 .0000 to 40 .00 l/s (110V, 60 Hz)
Resolution: 0 .0001 l/s to 0 .3000 l/s, 0 .001 l/s
to 3 .000 l/s, 0 .01 l/s > 3 .00 l/s
Accuracy: ± 0 .0009 l/s or ± 5 % of the test
value, whichever is greater

• Multilingual user interface (German, English, French,
Swedish)
• The device directly displays the current flow rate
without the need for analysis .
• The airtightness is evaluated on the basis of the
airtightness classes defined 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 .
