Description

CalMaster
World Leader in Leak Detection Technology


ISO 9001 Registered 

A user friendly transfer standard for the fast and accurate calibration of production leak detectors. NIST traceable. Can be used to calibrate pressure, flow, or vacuum type leak detectors.
 

Two flow ranges are available:
 CM-15 : 0.25 ~ 19.99 sccm
 CM-25 : 0.025 ~ 1.999 sccm 
 

Products Informaiton


Technology 
ㆍThe LNTech CM-15 & CM-25 CalMasters are used to induce airflow leaks in calibrating leak detectors.
ㆍThe instruments use a proprietary mass flow sensor to measure the flow of air from the leak detector’s calibration port or leak test fixture.

ㆍIn calibration mode, the calibration port is connected to the inlet (PRESSURE) port of the CalMaster. 
ㆍAir flows through a precision needle valve, across the mass flow sensor and out to atmosphere.
ㆍThis flow is measured and displayed on the DRO (digital read out).
ㆍThe leak rate is adjusted by varying the setting of the needle valve.
ㆍCalibration of vacuum type leak detectors is similar, except the calibration port is connected to the CalMaster outlet (VACUUM) port, and the inlet (PRESSURE) port is left open to atmosphere. 
ㆍCalibration of downstream (bell jar) leak detectors - a supply pressure must be connected to the inlet(PRESSURE) port, while the outlet (VACUUM) port is connected to the calibration port on the leak fixture. This will simulate a leak flow in to the bell jar.
