Frequently Asked Questions (FAQ)
QWhat measurement principle does the LMS-DOS100C dissolved oxygen sensor use?
AThe LMS-DOS100C uses fluorescence optical technology. It features a chemically-treated fluorescent membrane that reacts with dissolved oxygen in water, enabling highly accurate and stable DO measurements without consuming oxygen during the process.
QIs the LMS-DOS100C suitable for saltwater or high-salinity aquaculture environments?
AYes. The sensor is specifically optimized for harsh aquaculture environments including high-salinity and organically polluted water bodies. Its anti-biofouling fluorescent membrane and 316L stainless steel / titanium construction ensure reliable performance in demanding marine and brackish water conditions.
QWhat communication protocol does the sensor support and how is it powered?
AThe LMS-DOS100C supports RS-485 interface with MODBUS protocol, making it easy to integrate into existing aquaculture monitoring and control systems. It operates on 9-24VDC, with 12VDC recommended for optimal performance.
QHow accurate is the dissolved oxygen measurement and does it include temperature compensation?
AThe sensor provides a DO accuracy of ±0.3mg/L with a measurement range of 0–20mg/L. It features a built-in temperature sensor with accuracy <0.3℃, providing automatic temperature compensation to ensure reliable readings across varying aquatic conditions.
QHow often does the fluorescent membrane need to be replaced or maintained?
AThe fluorescent membrane is designed with scratch resistance and bacteriostatic properties for extended service life in aquaculture environments. Maintenance intervals depend on deployment conditions, but the anti-biofouling design significantly reduces the frequency of cleaning and replacement compared to traditional electrochemical membranes.
