Product Description:
The DX-DO3000 Online Dissolved Oxygen Meter from Wuxi Daoxin Technology Co., Ltd. is an advanced monitoring instrument specifically engineered for hygienic and clean-in-place (CIP) environments, making it ideal for the food and beverage industry. From fermentation processes to final water quality control, the analyzer delivers precise and continuous dissolved oxygen (DO) measurements that are essential to both quality assurance and process optimization.
The instrument supports both luminescent (optical) and membrane-based sensing methods. The optical sensor uses cutting-edge fluorescence technology that requires no membrane replacement or electrolyte replenishment, offering long-term stability and zero drift in high-sugar or organic-rich environments. For cost-sensitive setups, the membrane sensor offers replaceable diaphragms with consistent accuracy under controlled operating conditions.
With a resolution of 0.01 mg/L and a fast response time of ≤10s, the DX-DO3000 provides real-time oxygen tracking essential to dynamic fermentation processes, especially in beer brewing, dairy fermentation, soy product production, and bottled water operations.
Its automatic temperature compensation (0–80°C) ensures stability in rapidly changing environments such as CIP cycles or heat-sterilized pipes. With output support for 4-20mA and RS485 (Modbus RTU), the device easily connects to SCADA systems and digital PLCs used throughout automated food processing lines.

Applications:
In beer and wine fermentation, the DX-DO3000 helps manage dissolved oxygen during wort aeration, yeast propagation, and anaerobic phases. Its fast response and accuracy allow brewers to prevent oxygen oversaturation or depletion, both of which impact taste, clarity, and alcohol yield.
In dairy production, the device assists in maintaining strict oxygen thresholds in fermentation tanks, particularly for yogurt and cheese production, where even slight DO deviations can alter texture and microbial activity. It also supports real-time DO monitoring in cleaning rinse cycles, ensuring hygiene standards are met before reintroducing product flow.
For bottled water and beverage production, where ultra-low oxygen content is necessary to avoid oxidation or spoilage, the DX-DO3000’s high precision (±0.1 mg/L) allows effective control before packaging. It is also useful in monitoring water used in ingredient dilution, syrup mixing, and CO₂ dosing systems.
The analyzer is commonly installed in pure water loops, particularly in food-grade RO systems, where DO readings verify the absence of biological growth potential. Its 316 stainless steel construction and optional hygienic mounting accessories make it suitable for high-sanitization requirements.
Support and Services:
Wuxi Daoxin Technology provides specialized services tailored to food-grade applications. We offer hygienic-grade fittings, sanitary sensor holders, and CIP-compatible probe designs. Our team works closely with system integrators to ensure seamless deployment into existing factory control systems.
We support FDA-compliant material certification for probe housings and offer custom integration services for high-purity water skids, fermentation tanks, and inline quality control points. Customers can also request IQ/OQ/PQ documentation support for validated environments.
We provide remote calibration assistance, scheduled maintenance plans, and multi-point quality audits. For customers with stringent traceability requirements, we offer data logging modules that retain DO readings with timestamps for batch verification.
With the DX-DO3000, food producers can ensure product consistency, meet hygiene regulations, and reduce manual testing during every production cycle — from raw water entry to the final packaging line.
