Key features

Unlike polarographic DO sensors, the fluorescence principle measures oxygen without consuming it, eliminating electrolyte maintenance and membrane fouling issues common in electrochemical alternatives

By comparing the phase difference with the internal calibration value, it has a faster response speed, stronger anti-interference ability, and higher accuracy than the polarographic method.

Available in separate freshwater and seawater versions, with salinity compensation built in, since higher salinity directly reduces dissolved oxygen concentration at the same saturation percentage.

Fully submersible to IP68 with 0.6MPa pressure tolerance, supporting deployment at significant water depths in rivers, aquaculture tanks, reservoirs, and coastal seawater monitoring stations.

Measures from 0 to 20mg/L with 0.01mg/L resolution and 0.1% saturation resolution, capturing fine dissolved oxygen fluctuations critical for aquaculture and wastewater treatment control.

Integrated temperature measurement at plus or minus 0.5 degrees C accuracy enables real-time automatic temperature compensation, since DO saturation concentration changes significantly with water temp

Draws only 0.2W across a wide DC 10 to 30V supply range, enabling solar or battery-powered deployment in remote fish ponds, wetlands, and off-grid water quality monitoring stations.

Uses imported premium fluorescent membrane rated for 1 year of normal use. Only the membrane cap requires periodic replacement, keeping long-term consumable costs extremely low.

Electrode features NPT 3/4 threading compatible with Renke waterproof pipes, allowing the cable to be routed through the pipe for a clean, protected installation in harsh aquatic environments.

Supports zero oxygen and 100% saturation two-point calibration through free PC configuration software, with step-by-step in-software guidance.

AI-Powered supplier vetting

SummarySHANDONG RENKE CONTROL TECHNOLOGY CO., LTD. is identified as a Jinan-based trading company operating in manufacturing-related industries, including integrated circuits and environmental monitoring instruments. The supplier reports ISO9001:2015, RoHS, CE, and FCC certifications. It provides extensive customization and ODM services, has introduced new products within the past year, and reports OEM service for well-known brands. Production-related information includes sensor productivity of 400,000 pieces and five quality inspectors, although finished-product inspection has instructions but no written records. The supplier lacks inventory, overseas warehouses, overseas agents or branches, and a valid manufacturing-capacity contract with affiliated subcontractors. Financial records are referenced for 2022–2024, but no monetary figures or detailed financial indicators are provided. Customer evidence is limited to one associated buyer name and does not establish the scope or quality of completed projects.

CertificationsThe supplier reports an ISO9001:2015 certificate and product certifications including RoHS, CE, and FCC. These certifications explicitly support quality-management and product-compliance capability.

After-Sales capabilityThe supplier reports no inventory capability, no overseas warehouse, no overseas showroom, and no overseas agents or branches. It also reports serving zero countries overseas, so the provided evidence does not demonstrate strong after-sales coverage, particularly internationally.

R&D capabilityThe supplier reports new products within the past year, provides ODM services, and offers customization from samples, designs, and full specifications. However, it reports no available SDK, so innovation capability is supported in product development and design services but not across all technical-development resources.

Production capacityThe supplier reports sensor productivity of 400,000 pieces, five quality inspectors, and production equipment including an MST mounter and auto-soldering and soldering capabilities. Nevertheless, it has no valid manufacturing-capacity contract with affiliated subcontractors, and its inspection and supplier-assessment procedures lack written records, limiting assurance of production control.

Customization capabilityBoth reported design-service fields list customization from samples, designs, full customization, minor customization, and flexible customization. The supplier also reports ODM capability, providing explicit evidence of broad customization support.
