The Model 3681 Depth Gauge Test Chamber is used to stimulate the operating conditions necessary for accurate testing of depth gauges used in various military and commercial applications. Constructed of heavy-gauge aluminum, this hermetically sealed chamber incorporates a mounting fixture compatible with Type 1156 depth gauges in compliance with MIL-G-18067C specifications.
A large acrylic window in the test chamber end permits convenient observation of the unit under test, and an electrical feed-through enables electrical connections inside the chamber. The chamber also incorporates a pneumatic feed through that can be used for supplying pressure to the unit under test.
Safety features include an interlock that prevents the door from being opened when the chamber is pressurized and a relief valve that automatically vents excess pressure.
