❓ Frequently Asked Questions
Q
What is the difference between a fluorescence DO sensor and a traditional electrochemical DO sensor?
A fluorescence DO sensor uses optical technology to measure dissolved oxygen without consuming oxygen during the process, whereas traditional electrochemical sensors consume oxygen and require regular membrane and electrolyte replacement. Fluorescence sensors offer greater stability, lower maintenance, and longer service life.
Q
Does the fluorescence DO sensor require frequent calibration?
Fluorescence DO sensors are highly stable and typically require less frequent calibration compared to electrochemical sensors. A simple one-point or two-point calibration in air or water-saturated solution is usually sufficient before use or periodically during long-term deployment.
Q
Is this portable DO sensor suitable for aquaculture use?
Yes. The portable fluorescence DO sensor is specifically well-suited for aquaculture environments such as fish ponds, shrimp farms, and recirculating aquaculture systems. Its waterproof design, fast response, and low maintenance make it an ideal choice for daily water quality monitoring in aquaculture operations.
Q
Does the sensor compensate for temperature changes automatically?
Yes. The sensor features built-in automatic temperature compensation (ATC), which ensures accurate dissolved oxygen readings across varying water temperatures without the need for manual correction.
Q
What is the waterproof rating of this portable DO sensor?
The portable fluorescence DO sensor carries an IP67 waterproof rating, meaning it is fully protected against dust and can withstand temporary immersion in water. This makes it reliable for outdoor fieldwork, aquaculture ponds, and other wet environments.
Q
How long does the sensor cap or sensing element last before replacement?
The fluorescence sensing cap is designed for long-term use and typically lasts significantly longer than traditional electrochemical membranes — often 1 to 2 years or more under normal operating conditions. Replacement intervals depend on usage frequency and environmental conditions.
