Touch Screen Air Tightness Leak Detector Air Leakage Tester
1. Use
The LR-230 series air tightness tester adopts the direct pressure
principle and uses air as the medium to detect the leakage of
products. It is a kind of non-destructive testing instrument. The
working principle is to inflate the test product to the specified
air pressure, then close the valve, stabilize it for a period of
time, measure the change in air pressure during the test, and
calculate the leakage through conversion. This instrument features
high precision and comprehensive functions, and is widely used for
sealing detection of parts in open or closed products.
2. Functional features
1. 7 inch touch screen display, Chinese and English language
switch.
2. Large leakage, small leakage 2 alarm functions.
3. Alarm set, self-setting,Leakage pressure cap,Test pressure lower
limit
4. Usb disk history storage, query, print, delete, screenshot
5. Data storage, the instrument can store test results 24 hours a
day
6. Test time can be set for each stage (0.1s-999s)
7. External control, do not need to use PLC program to achieve
cylinder control
3. Application fields
It is widely applied in fields such as electronic consumer goods,
smart clothing, wires, the automotive and motorcycle industries,
the battery industry, valves and pipe fittings, connecting pipes,
solenoid valves, lighting fixtures, fire-fighting equipment,
household appliances, etc.
