Calibrated Leaks from LACO Technologies

LACO manufactures a wide variety of CalMaster™ leak standard designs. Most leak standards ship within 3 weeks or less which minimizes your process down time. CalMaster™ leaks feature:

Fast Delivery
Rugged and Reliable
Both Standard & Custom Designs
Broad Range of Designs, Leak Rates, & Gases
Responsive Technical Support Staff

NIST Traceable
In addition all LACO leak standards are backed by our lifetime product warranty and include a NIST traceable, A2LA accredited calibration certificate to ISO 17025-2005 and ANSI Z540-1-1994 standards.

Innovative Leak Element
Most LACO CalMaster™ leak standards now feature our proprietary micro tube capillary leak elements. Learn more about the benefits of LACO's micro tube capillary leaks in the benefits tab.
