Description
Overview
GAOTek aqua fluor optical dissolved oxygen sensor & fluorescence method meter multi parameter simultaneous display oxygen value, temperature, output current, alarm point and so on. Visually readable and with a range of overrun hints. The alarm status is displayed on the screen, and the output of the switch ON signal can be simultaneously connected. Communication function (optional): RS485 communication interface (MODBUS Protocol Part compatible), 4 to 20 mA current output corresponding to the DO value can be arbitrarily set, Arbitrary setting function of hysteresis, Avoid frequent action of switch and relay.
