CX-IDO-1304A Industrial Dissolved Oxygen Meter

 

CX-IDO-1304A Industrial Dissolved Oxygen Meter is a high-intelligence on-line continuous monitor made by our company. It can be equipped with CX-IDO-130F polarographic electrode, achieving the wide-range measurement from ppb level to ppm level automatically; and it is a special instrument for measuring oxygen content in the liquid in boiler feed water, condensate water, environmental protection sewage and other industries. Relying on its quick response, stability, reliability, low usage cost and other features, CX-IDO-130F Dissolved Oxygen Electrode is suitable for the large-scale use by the customers.

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

Automatic conversion of measuring frequency: The electrode polarization is avoided and thus the

measurement accuracy is improved.

Alarm: Alarm signal isolation output; the alarm upper and lower limits can be arbitrarily set and the alarm is

undone in hysteresis.

Network function: Isolated current output and DRS485 or RS232 communication interface.

Isolated current output: The current is corresponding to the output upper and lower limits of the dissolved

oxygen values, which can be arbitrarily set.
