AURA Systems Update:

Dear Customer,

As a leader in production leak testing technology, LACO continues to develop solutions to meet the needs of many industries and applications. In order to focus on bringing the most innovative products in tracer gas leak detection, LACO has decided to discontinue manufacturing our line of AURA air leak testing instruments.

Effective March 31, 2023 we will no longer accept orders for the AURA family of products. We will continue to offer technical support, parts, and service for these products for years to come. For new applications, we will be happy to provide recommendations and referrals to meet your air leak testing needs.

We look forward to continuing to provide helium and other tracer gas leak testing solutions
