Technician Operating CANT Data Acquisition Unit, San Francisco State College, November 1971

Primary Device (Left, marked CANT):

• CANT Data Acquisition System
• This unit likely controls and records measurements from experimental setups—such as a wind tunnel, pressure system, or other mechanical/thermal test rig.
• The rotary dials and switches allow the user to select channels and set parameters.
• The glass tube above appears to be part of a fluid or pressure interface, possibly feeding readings into the CANT system via transducers.

Secondary Device (Middle-Right):

• Beckman Type R Dynograph (or similar strip chart recorder)
• This device records voltage or current signals onto a long roll of paper.
• It was commonly used to track analog sensor data over time.
• This is consistent with a lab analyzing fluid mechanics, structural responses, or pressure variations.
