Online DO dissolved oxygen meter
High Quality cheap DO probe/DO Meter/Dissolved oxygen controller sensor water tester
0-20mg/L, automatic range switching; 0-60℃
±0.5% FS, ±0.3℃
Automatic temperature compensation:
two sets of normally open relay contact, divided into high and low alarm signal, photoelectric isolation output
Signal isolation output:
photoelectric coupler isolated protection 4-20mA signal output
arbitrary setting of hysteresis, relay load 3A 220VAC
ambient temperature of 0-60℃, relative humidity ≤ 90%
Cut off dimensions:
● Multi parameter simultaneous display: oxygen value, temperature, output current, alarm point and so on. Visually readable and with range 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): RS-485 communication interface (MODBUS Protocol Part compatible), 4-20 mA current output corresponding to the DO value can be arbitrarily set
●Arbitrary setting function of hysteresis, Avoid frequent action of switch and relay.
●Watchdog function: Make sure the instrument does not crash.
● The core components come from famous foreign brands.
