The TC-10 is portable test chamber designed to test up to 10 military Altimaster altimeters. The unit is housed in a Pelican 1600 case.The pump runs continuously, and when the test chamber is being loaded with altimeters, the pump is creating a vacuum in a reservoir inside the test chamber. The use of a vacuum reservoir allows for a more rapid climb to altitude.The TC-10 is a "vacuum only" chamber and tests from ambient altitude to 30,000 feet MSL.Unless otherwise specified the TC-10 is supplied with a 110V pump, other voltages available on request.

Operation Manual

The TC-21 is portable test chamber similar in appearance to the TC-10, however the TC-21 is designed to test up to 10 military Altimaster altimeters over a complete range of altitudes, regardless of ambient altitude.

The TC-21 using both vacuum and positive pressure sources to test from -1000 feet to 30,000 feet MSL.

This test chamber is designed for users who are testing altimeters at an ambient altitude significantly above zero MSL.

Unless otherwise specified the TC-21 is supplied with a 110V pump, other voltages available on request.
