Key features

Uses non-dispersive infrared (NDIR) sensing principle to measure CO2 concentration with high sensitivity, excellent repeatability, and no electrochemical degradation over time.

Selectable ranges of 0 to 2,000 ppm, 0 to 5,000 ppm, or 0 to 10,000 ppm cover indoor air quality, agriculture, and high-concentration industrial applications.

Internal temperature compensation minimizes reading drift caused by ambient temperature fluctuations, ensuring stable accuracy across varying field conditions.

Supports RS485, 4 to 20mA, 0 to 5V, and 0 to 10V outputs in a single product line, compatible with PLCs, data loggers, and SCADA systems out of the box.

Each sensor is calibrated before shipment. Customers do not need to perform secondary calibration, reducing setup time and eliminating calibration equipment costs.

An optional OLED display module can be added for on-site real-time data viewing without connecting to external devices or software.

The breathable membrane on the sensor shell allows free gas circulation to the sensing element while blocking moisture and dust from reaching internal components.

Under normal use, the sensor lasts up to 5 years. Only the breathable membrane requires annual replacement, keeping long-term maintenance costs extremely low.

Available as wall-mounted, duct-mounted, handheld, fixed explosion-proof, and outdoor radiation-shield versions, covering virtually every CO2 monitoring scenario.

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.
