Watch this hands-on demo of the Yokogawa FLXA402 4-wire multi-channel liquid analyzer — a direct replacement for failed converters. We show the color touch display, walk through pH, ORP, conductivity and dissolved oxygen input modules, and demonstrate 4-20 mA HART and RS-485 Modbus integration. See how existing sensor cabling and output wiring stay unchanged, plus a quick look at the factory-sealed unit, testing steps and 3-5 day stock shipping.
