DOG-2092A Industrial online Dissolved Oxygen Meter
DOG-2092A Industrial online Dissolved Oxygen Meter is a high-intelligence on line continuous monitoring instrument developed by our company. DOG-209F (ppm grade) Relying on its quick response, stability, reliability, low usage cost and other features, large-scale used.
Features
Computer-based: It adopts high-performance CPU chip, high-precision AD conversion technology and SMT to |
complete multi-parameter measurement, temperature compensation and automatic range switching, with high |
precision and good repeatability. |
Reliability: Touch button, no switch knob or potentiometer. |
Alarm: Alarm signal isolation output; the alarm upper and lower limits can be arbitrarily set and the alarm is |
undone in hysteresis. |
Isolated current output: The current is corresponding to the output upper and lower limits of the dissolved oxygen |
values, which can be arbitrarily set. |
