Replaces / Drop-In Replacement For
The model number 520-7.9scc/m-195.0psig-21 is a specific, non-duplicate part. Verify exact compatibility with your system integrator or CTS technical support before substitution. Similar CTS 520-series calibrated leak standards exist with different flow rates and pressures (e.g., 520-2.0scc/m, 520-15.00scc/m, 520-40.00scc/m) but are not direct drop-in replacements due to flow rate differences.
Works With
- CTS leak detection software and data logging systems
- Standard pressure measurement instruments (gauges, transducers, PLCs)
- Compressed air and inert gas supply systems
- Digital multimeters and data acquisition devices for leak rate verification
- ISO/IEC 17025 test protocols and traceability documentation
