EXHIBIT 5.1

September 7, 2005

QualMark Corporation
4580 Florence Street
Denver, CO 80238

Gentlemen:

I have acted as counsel to QualMark Corporation ("Company") in connection with
the preparation and filing of a Registration Statement on Form S-8
("Registration Statement") covering registration under the Securities Act of
1933 of 300,000 shares of the Company's Common Stock, no par value per share
("Shares"). The Shares offered are 300,000 shares offered pursuant to the
QualMark Corporation 2005 Stock Option Plan. As such, I have examined the
Registration Statement, the Company's Articles of Incorporation, as amended, its
Bylaws and minutes of its Board of Directors.

Based on the foregoing, and assuming that the Shares will be sold according to
the Registration Statement at a time when effective and that there will be
compliance with all applicable securities laws involved in those states in which
the shares may be sold, I am of the opinion that, upon issuance of the Shares
according to the Registration Statement and receipt of the consideration to be
paid for the Shares, the Shares will be validly issued, fully paid and
nonassessable shares of Common Stock of the Company.

I consent to the use of this opinion as an exhibit to the Registration
Statement.

Sincerely,


/s/ Cynthia King
