Factory Tour

ISO-Certified Quality Management 
Operating under strict ISO9001 Quality Management and ISO14001 Environmental Management Systems, our manufacturing facility ensures that every water quality sensor, online monitoring system, and water level meter complies with international industrial standards.

Core Electrode Technology & In-House R&D
As a dedicated R&D manufacturer, our core competency lies in the advanced development of sensor electrodes, automated data collection modules, and seamless system integration. This full-stack capability allows us to maintain superior performance and high stability from the hardware level up.

Mass Production & Diverse Portfolio
Equipped with specialized testing and calibration laboratories, we mass-produce an extensive portfolio of over 50 types of advanced monitoring equipment—including digital pH, DO, Turbidity, COD, Ammonia Nitrogen sensors, and heavy-duty ultrasonic/pressure water level meters.

Rigorous Testing & Calibration 
Before leaving our plant, every sensor undergoes a meticulous multi-point calibration process and simulated field-environment testing (covering extreme water temperatures, pressure variations, and drainage pipeline simulated networks) to guarantee long-term drift-free accuracy.

OEM & ODM Tailored Services

At Shenzhen Kainafu Technology Co., Ltd., we don’t just offer standard catalog products—we deliver highly flexible and scalable OEM (Original Equipment Manufacturer) and ODM (Original Design Manufacturer) solutions. Whether you need a simple private-label sensor or a fully customized cloud-integrated water monitoring station, our experienced engineering team is here to bring your concepts to life.

Our Core Customization Capabilities:

• Sensor & Electrode Customization: Custom modification of pH, DO, Turbidity, COD, and Ammonia Nitrogen sensor electrodes (materials, measurement ranges, and dimensions) to withstand specialized or harsh industrial environments.

• Hardware & Firmware Engineering: Tailored data collection modules, custom PCB layouts, and multi-protocol firmware adaptation (RS485 Modbus RTU, 4-20mA, SDI-12, NB-IoT, LoraWAN, 4G).

• Structure & Appearance Design: Custom housing materials (such as anti-corrosive POM, Titanium, or 316L Stainless Steel), private-label laser engraving, logo branding, and customized industrial packaging.

• Software & Cloud Integration: Custom API/SDK protocols for seamless data streaming into your existing SCADA systems, third-party management software, or a personalized version of our Water Quality Data Cloud Platform.

Why Partner with Kainafu for OEM/ODM?

• ISO 9001/14001 Quality Standards: Every custom batch undergoes strict multi-point calibration, waterproof sealing tests, and aging simulation in our specialized laboratories.

• Flexible MOQ & Rapid Prototyping: We support system integrators with low Minimum Order Quantities (MOQ) for initial evaluation and provide fast turnaround on functional prototypes.

• IP Protection Guaranteed: We strictly respect and protect our clients' intellectual property rights, offering NDA (Non-Disclosure Agreement) protection for all custom-developed technologies.
