                  FILE NO. 1-09327

Dear Mr. Vaughn and Mr. Burton:

         On July 19, 2008, we submitted a letter to the Securities and Exchange
Commission (the "SEC") and Universal Detection Technology's (the "Company")
Amendment No. 1 to Form 10-KSB for the fiscal year ended December 31, 2007 (the
"Amended Annual Report") and Amendment No. 2 to Form 10-Q for the quarter ended
March 31, 2008 (the "Amended Quarterly Report"). The Amended Annual Report and
the Amended Quarterly Report contain revisions that were made in response to the
comments received from the staff ("Staff") of the SEC on May 6, 2008. In
connection with responding to Staff comments the Company failed to provide a
written acknowledgment as requested by the Staff in the May 6, 2008 letter.
Accordingly, please find attached the Company Certification and Acknowledgment
as requested in your May 6, 2008 letter.

         We hope that the acknowledgment attached to this letter satisfactorily
addresses the comments and requests by the Staff. Should you have any further
questions regarding the above, please contact the undersigned at 310-248-3655 or
by fax at 310-273-2662.

                                        Very truly yours,

                                        UNIVERSAL DETECTION TECHNOLOGY
