CX-IDO-1301A Industrial Dissolved Oxygen Meter

CX-IDO-1301A Industrial Dissolved Oxygen Meter is a kind of on-line instrument that is used for water quality analysis and monitoring and is equipped with a microprocessor. It is widely used for continuous monitoring of the dissolved oxygen content of various solutions used in power plants and biological and chemical industries. The high-temperature sterilized dissolved oxygen electrode produced by our company can also be used in bio-fermentation industry.

Features:  

Large vacuum fluorescent display (VFD), Chinese menu, and man-machine interaction function.

There are application analysis for the electrode and four calibration methods.

The functions of automatic temperature compensation and automatic range switching.

Available with history curve, real-time trend chart and clock.

There are four kinds of built-in recorders. It is available with isolated current output and alarm.

The user can set the password or consult the “Help” menu or the “Service Guide” Menu.

It has power-off protection. The data can be saved for 5 years under a continuous power-failure condition.

The communication interface can be connected directly to a computer and enables remote operation and control.

The instrument adopts universal module power supply.

It is equipped with the dissolved oxygen electrode with excellent technical performance and stable and reliable

measuring capacity. It can be easily used and maintained.
