Plant 4, No. 188, Guanghua Road, Minhang Dist., Shanghai, China (Mainland)
96*96*115mm (Dimension)
In computer storage, such as dissolved oxygen pressure, salinity characteristics, probe slope deviation etc..
Function menu selection, high and low alarm, hysteresis adjustment.
The removal of the electrode during calibration does not disturb the control process. (without mutation transmission)
Isolated 4~20mA output current with operating error indication, with Apure dissolved oxygen electrode more accurate (only DO dissolved oxygen).
Large screen LCD display, easy to operate, clear at a glance.
