Oxi296 belongs to the QuadroLine series of products. It has a small size, multiple functions, is suitable for panel installation and precise DO testing, and is specifically designed for industrial inspection. Based on the same advanced microprocessor technology as the EcoLine series, it has all the necessary features for outdoor installation instruments, such as built-in lightning/overvoltage protection circuits, electrical isolation between inputs/outputs, and effective EMC protection, OxiCal? Single point calibration and built-in system diagnostic function. It can be said that Oxi296 is a low-cost and high-performance dissolved oxygen controller. Oxi296 is capable of handling all occasions, with up to 32 options that allow users to choose the functions of the monitoring device according to the actual conditions on site, greatly saving unnecessary expenses. WTW also provides a set of components that can combine the entire QuadroLine series of instruments, such as pH, DO, Cond., to form a flow monitoring system.

Power overvoltage protection
QuadroLine Oxi296, like the EcoLine series, adopts advanced and effective overvoltage protection technology. Its electronic circuit can protect the entire testing system (including the host and electrodes) installed outdoors from transient overvoltage and lightning damage. Therefore, users do not need to install additional protective devices, saving costs, while other brands of instruments require external protective devices to operate reliably.

Excellent EMC protection effect


Large size digital display screen
LCD reading is easy, with dual row display of test values and the ability to display warning codes, indicating the location of the fault to the user.

Electrode diagnosis
Oxi296 has advanced electrode self diagnosis function. When the electrode has a fault, the corresponding alarm relay will be activated, and the electrode status will be displayed on the LCD.

Dual channel analog output
Oxi 296 has two sets of analog outputs, representing DO and temperature values, with fully adjustable ranges and adjustable attenuation coefficients for smooth output.

Programmable relay
Two sets of relays can be set through a menu, and different control and alarm functions can be specified according to specific applications.

RS485 serial interface
The RS485 bidirectional interface can form a small network, allowing access to up to 31 QuadroLine instruments to form a central control system for remote data transmission. If another special gateway is connected, this bus control system can also be connected to PROFIBUS-DP.

Wide range of model selection
Oxi 296 has 32 models to choose from, each suitable for different occasions. Among them, the 24VDC/VAC model allows battery power supply and is suitable for field monitoring.

Menu based operation
The user interface is well-organized and structured, including LCD display, simple buttons, and programmed menus. Even inexperienced users can complete settings, calibration, and other operations.
