D-Opto Sensor

The D-Opto consists of a probe that incorporates the dissolved oxygen sensing element, temperature thermistor, and processing electronics in a tough high impact resistant body.

All the calibration coefficients, serial number and SDI-12 address are stored on-board the probe in non-volatile memory.

D-Opto;

• Outputs temperature, percent saturation and ppm
• Digital output signal enables long cable run without signal deterioration
• SDI-12 signal output as standard
• Low power requirement; 0.2mA in standby, 10mA during sampling
• Reverse polarity and fully surge protected
• Copper bio fouling control ring around the optical window
• Highly flexible, abrasion resistant, fully waterproof EPDM jacketed cable
• Windows software for sensor calibration
• Interface board as standard for simple system integration
• Sensor life expectancy in excess of 5 years

The Interface;

The D-Opto is supplied with an interface board to simplify installation. The interface board features screw clamp terminals for connecting the D-Opto and power supply and data logger. The interface board also enables a laptop to be connected to the D-Opto WITHOUT having to disconnect the D-Opto from the data logger.

This enables the D-Opto to be checked and calibrated on-site, without the need for disconnecting any cabling.
