Optical Dissolved Oxygen measurementsThe 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
- 4-20mA optional
- 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.
