This is a non-competitive FAR Part 12 notice to acquire a Tenny Cevo-20S environmental test chamber to replace an existing Tenney chamber. The specified model is required because replacement parts are unavailable, alternative chambers are too large for the lab space, and other options require 3-phase or 480V power that the facility lacks. The chamber must accommodate whole instruments, preferably two at once, to expedite testing. Responsible sources that believe they can meet the requirement may submit a capability statement for government consideration. The government may decide not to compete based on responses, and will not reimburse any costs incurred in responding.
