About arduino ph sensor
Where to Source Arduino pH Sensor Suppliers?
China remains the central hub for electronic sensor manufacturing, with key industrial clusters in Hunan, Sichuan, Zhejiang, and Beijing offering specialized capabilities in environmental monitoring devices. Hunan and Sichuan provinces host advanced R&D centers focused on smart agriculture and water quality instrumentation, enabling rapid prototyping and integration with microcontroller platforms like Arduino. The Beijing-Tianjin region supports high-precision production lines with access to semiconductor fabrication resources, enhancing signal stability and measurement accuracy in pH sensing modules.
These regions benefit from vertically integrated supply chains—spanning electrode materials, circuit board assembly, and calibration systems—allowing for efficient scaling and reduced component lead times. Suppliers leverage localized logistics networks to achieve average delivery cycles of 15–25 days for standard orders. Buyers gain access to flexible production models capable of fulfilling low-volume prototypes (MOQ as low as 1 piece) or bulk deployments (up to 100+ units), with cost advantages of 20–35% compared to Western-based manufacturers.
How to Evaluate Arduino pH Sensor Suppliers?
Adopt a structured assessment framework when selecting suppliers:
Technical Competence & Compliance
Confirm adherence to international standards such as RoHS for hazardous substance control and CE marking for electromagnetic compatibility. While ISO 9001 certification is not universally declared, prioritize suppliers demonstrating documented quality management processes, particularly in calibration procedures and long-term drift testing. Request validation reports for pH accuracy (typically ±0.1–0.3 pH units) and temperature compensation ranges.
Production & Customization Capacity
Assess supplier infrastructure through available indicators:
- Minimum order quantities ranging from 1 to 20 pieces indicate flexibility for prototyping and small-batch procurement
- Customization options including output types (analog, UART, RS485), cable length, probe material (epoxy, stainless steel, plastic), and labeling
- In-house design capability confirmed by product variants tailored for soil, water, or industrial wastewater applications
Cross-reference response time (≤2–6 hours) and on-time delivery rates (>93%) as proxies for operational efficiency and order prioritization.
Transaction Reliability & Risk Mitigation
Analyze reorder rates (<15% to 25%) to gauge customer retention and post-sale satisfaction. Favor suppliers with response times under 2 hours and documented online revenue exceeding US $100,000, indicating established commercial operations. Conduct sample testing to verify linearity across pH 0–14 range and resistance to fouling in high-salinity environments before full-scale ordering.
What Are the Leading Arduino pH Sensor Suppliers?
| Company Name | Main Products | On-Time Delivery | Reorder Rate | Avg. Response | Online Revenue | Customization | Min. Order Flexibility | Price Range (USD) |
|---|---|---|---|---|---|---|---|---|
| Hunan Firstrate Sensor Co., Ltd. | Pressure Sensors, Level Instruments, Temperature Devices | 98% | 23% | ≤2h | $610,000+ | Color, material, size, logo, packaging, label, graphic | Moderate (5–20 pcs) | N/A |
| Chengdu Sentec Technology Co., Ltd. | Environmental Sensors, Gas Analyzers, Test Instruments | 100% | <15% | ≤6h | $120,000+ | Limited customization | High (1 pc) | $15–20 |
| Ningbo Better Technology Co., Ltd. | pH Meters, Water Quality Testers, Refractometers | 100% | <15% | ≤4h | $10,000+ | Plastic electrodes, in-line meters, portable testers | Low to moderate (20–100 pcs) | $2.50–4.50 (bulk) |
| Sichuan Weinasa Technology Co., Ltd. | PH Electrodes, ORP/EC Modules, Soil Testers | 93% | 25% | ≤5h | $110,000+ | Color, size, logo, packaging, label, graphic | Low (1 set) | $158 |

Performance Analysis
BGT Technology leads in volume production and technical flexibility, supported by the highest reported online revenue and comprehensive customization scope. Its sub-2-hour response time and 100% on-time delivery reflect strong operational discipline. Chengdu Sentec stands out for low MOQs, offering entry-level pricing at $15–20 per unit, ideal for prototype development despite lower reorder metrics. Sichuan Weinasa commands premium pricing ($158/set) but shows the highest reorder rate (25%), suggesting strong end-user satisfaction. Hunan Firstrate and BGT emphasize industrial-grade materials and scalable production, suitable for agricultural automation and municipal water monitoring deployments. Ningbo Better provides the lowest per-unit cost in bulk configurations, though with higher minimum thresholds.
FAQs
How to verify Arduino pH sensor supplier credibility?
Request evidence of calibration protocols, electrode lifespan data (e.g., 1–2 years under normal use), and compatibility documentation with common Arduino boards (Uno, Mega, ESP32). Validate claims through independent lab reports or field-test references where available.
What is the typical lead time for samples?
Sample fulfillment generally takes 7–15 days, depending on complexity. Basic analog sensors ship faster, while digital outputs with RS485 or Zigbee interfaces may require additional programming and testing, extending timelines to 20 days.
Do suppliers support global shipping?
Yes, all listed suppliers have international transaction histories. Confirm Incoterm preferences (FOB, EXW, CIF) and ensure packaging meets export standards for electronic components. Air freight is recommended for samples; sea freight optimizes cost for containerized orders.
Are free samples available?
Most suppliers offer paid samples, with costs recoverable against future bulk orders. Free samples are rare but possible for high-potential buyers committing to volumes exceeding 50 units. Sample fees typically cover 30–50% of unit production cost.
How to initiate custom design requests?
Submit detailed specifications including measurement range (pH 0–14 standard), output signal (analog voltage, I2C, Modbus RTU), probe dimensions, immersion depth, and operating environment (soil, liquid, wastewater). Suppliers with dedicated R&D teams can provide schematics and test data within 72 hours and deliver functional prototypes in 3–4 weeks.
