Combined Opinion and Consent

Ingen Technologies, Inc.
35193 Avenue "A," Suite-C
Yucaipa, California 92399

     RE:  INGEN TECHNOLOGIES, INC.

Gentlemen:

You have requested our opinion, as counsel for Ingen Technologies Inc., a
Georgia corporation (the "Company"), in connection with the registration
statement on Form SB-2 (the "Registration Statement"), under the Securities Act
of 1933 (the "Act"), being filed by the Company with the Securities and Exchange
Commission.

The Registration Statement relates to an offering of 14,142,068 shares of common
stock issuable in connection with the conversion of promissory notes to be sold
by enumerated selling shareholders.

We have examined such records and documents and made such examination of laws as
we have deemed relevant in connection with this opinion. It is our opinion that
the shares of common stock to be offered pursuant to the Registration Statement
and sold by the selling shareholders have been duly authorized and shall become
legally issued, fully paid and non-assessable when the notes are converted and
the warrants are exercised and the underlying shares are issued.

No opinion is expressed herein as to any laws other than the State of Georgia of
the United States. This opinion opines upon Georgia law including the statutory
provisions, all applicable provisions of the Georgia Constitution and reported
judicial decisions interpreting those laws.

We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to our firm under the caption "Legal
Matters" in the Registration Statement. In so doing, we do not admit that we are
in the category of persons whose consent is required under Section 7 of the Act
and the rules and regulations of the Securities and Exchange Commission
promulgated thereunder.

Very truly yours,

ANSLOW & JACLIN, LLP
