Measuring equipment and testing machine

COSMOWAVE TECHNOLOGY

The LM-1C is designed and manufactured according to the specified test pressure and leak rate, accommodating a range of -89 kPa to 999 kPa. On the other hand, the LM-1AH is a high-pressure model capable of handling test pressures from 1 MPa up to a maximum of 4.9 MPa. These Leak Masters are precise, stable, and compact, making it easy to verify the sensitivity of air leak testers and measure equivalent internal volume.

■ Features

Manufactured with an accuracy within ±5% for leak rates of 2 mL/min or higher
Enables easy and reliable sensitivity checks for air leak testers
Maintains stable leak rates over long periods
Compatible with external pressure detection systems (secondary-side measurement)
Can be directly connected to calibration ports
Connectable to intermediate piping using a dedicated adapter
Traceability certificates available

■ Specifications
