Product introduction
smart storm water quality sensor optical dissolved oxygen temperatureOPTOD description:
Optical technology: The OPTOD sensor is based on cold light optical technology and is supported by ASTM International Standard Method D888-05. With no calibration requirements and extremely low power consumption technology, the OPTOD sensor is suitable for field work and short-term or long-term monitoring.
This technology does not consume oxygen and can measure accurately under any conditions, even at very low oxygen concentrations.
Digital technology: The 'smart' OPTOD sensor stores calibration history data within the sensor, allowing 'plug and play' systems without calibration.
