Key features

A single sensor delivers conductivity, TDS, salinity, and temperature readings simultaneously.

K=1 range 1 to 2000 uS/cm, K=10 range 10 to 20000 uS/cm, covering both low-conductivity purified water and high-conductivity industrial solutions.

Built-in temperature compensation with adjustable coefficient corrects conductivity readings in real time across the full measurement temperature range.

Fully waterproof to IP68 with 0.6MPa pressure tolerance, enabling continuous submersion in tanks, pipelines, rivers, and industrial process vessels without housing degradation.

One-piece construction eliminates loose components and external accessories, supporting both immersion installation via 3/4 thread waterproof pipe and direct inline pipeline connection.

RS485 Modbus-RTU communication baud rate is software-configurable, enabling seamless integration into existing multi-sensor RS485 networks.

Surface platinum black coating must not be wiped, only chemically cleaned with warm detergent, alcohol, or citric acid, preserving coating integrity and measurement accuracy long-term.

Under normal use conditions, recalibration is only recommended every 3 months, with frequency adjusted based on application fouling level.

Default 5m cable is customizable to any required length on order, enabling flexible routing in tanks, treatment basins, and pipeline installations without on-site cable splicing.

Sensor readings can be accessed via customer software or directly connected to Renke's portable water quality analyzer, supporting both fixed monitoring and mobile field inspection workflows.

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.
