※There is a LM-1C manufactured to the specified test pressure and leak volume, and a LM-1C-J1 Series with specified leak volume.
●Create the specified leak amount at the specified test pressure
●Manufacturing precision within 5% of the requested leak volume.
However, for less than 2mL/min, manufacturing precision should be ±10～20%.
●By changing the leak master to a dedicated seal plug, it is possible to easily return to normal inspection status (no leak status)
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/seal plug/filter element/O-ring)
Price 38,000 yen, taxes not included (0.1mL/min is 42,000 yen, taxes not included)
Cosmo Instruments displays the leak volume as “equivalent flow” and “conversion flow” The requested leak volume is manufactured with equivalent flow.
■E.FLOW（Equivalent Flow）: Flow measured at 20°C and 1atm. The flow is not affected by the environmental condition.
■C.FLOW（Conversion Flow）: Flow measured at the ambient temperature and pressure that is converted to the flow at 20°C and 1atm. Flow varies depending on the environmental condition
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)
＊M-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/seal plug/filter element/O-ring)
＊Purchase the adapter and seal plug when connecting Leak Master between tested part and WORK port.
