* Three models are available:
LM-1C: Customized to the specified pressure and flow, LM-1C-J1 series: Standard model with predetermined flow, LM-1AH for high pressure from 1 MPa to 4.9 Mpa.
● Accuracy (Difference from the required flow): Within ±5%
For 2 mL/min or less: Within ±10 to 20%.
* High pressure LM: For 0.1 to 0.7 mL/min: Within ±20%, For 0.8 to 50 mL/min: Within ±10%
● By replacing the Leak Master with the dedicated plug, the tester can easily return to the normal test state (no leak state).
The LM-1C Series is used as an ideal determination device, so it can be manufactured with your desired leak volume.Please specify test pressure and leak volume in the range below when ordering.
|Test Pressure||Leak volume|
|Positive pressure||1 ～ 9.9 kPa||0.1 ～ 20 mL/min|
|10 ～ 99 kPa||0.1 ～300mL/min|
|100 ～ 999 kPa(※1)||0.1 ～500mL/min|
|Vacuum pressure||-1 ～ -9.9 kPa||0.1 ～ 20 mL/min|
|-10 ～ -49 kPa||0.1 ～ 100 mL/min|
|-50 ～ -89 kPa||0.1 ～ 200 mL/min|
（※1）Test pressure 1MPa or above is supported with LM-1 AH special order.
Manufactured with requested leak volume in the below accuracy.
・For flow rate 2 mL/min or above, manufactured within ±5% accuracy
・For flow rate 0.8 mL/min or above, manufactured within ±10% accuracy
・For flow rate less than 0.8 mL/min, manufactured at ±20% accuracy
Configuration: LM-1C (with filter joint/clear cover)
Accessories (adapter/plug/filter element/O-ring)
LM-1C-J1 Series are standardized Leak Masters as shown on the table below.
A data sheet showing actually measured or calculated flows at the test pressure points in the table below will be enclosed.
This series are an ideal standard for the calibration of the air leak tester sensitivity.
■ Cells in gray are actually measured flow.
□ Cells in white are calculated flow.
(The flow rates in the table above are some examples)
＊LM-1C-J1 Series are manufactured within ±5% accuracy of each standard flow at test pressure of 100 kPa except for 1 mL/min.For flow rate 1 mL/min, manufactured within ±10% accuracy.
● Configuration:LM-1C-J1 (with filter joint/clear cover), Accessories (adapter/plug/filter element/O-ring)
＊Purchase the adapter and plug when connecting Leak Master between tested part and WORK port.
Use the LM-1AH for high pressure.
The pressure is available from 1 to 4.9 MPa. Check the specified flow at high pressure.
■ LM-1AH High Pressure Production Range
Test Pressure：1 to 4.9 MPa
Flow：0.1 to 50 mL/min
■ LM-1AH / Accuracy (Difference from the required flow) and minimum unit
|Required flow mL/min||Accuracy||Minimum unit mL/min|
|0.1 to 0.7||Within ±20%||0.1|
|0.8 to 19.9||Within ±10%||0.1|
|20 to 50||Within ±10%||1|
■ Main Body:LM-1C / LM-1AH (With a filter joint and an acrylic cover)
