Tech Network Systems is an independent dealer of certified used, refurbished and surplus-new industrial hardware — networking, automation, test and measurement, electrical and power, GPS and survey, servers and storage.
What "tested" actually means here
Every unit is function-tested on the bench before it is listed. We photograph the actual unit you will receive — not a stock render standing in for it. Serial numbers are verified against the chassis, and configurable gear is factory-reset before it ships.
