China’s New Calibration Standard for Urine Meters: What Foreign MedTech Founders Need to Know

China’s market regulator has issued a national metrology standard for urine meters used in ICUs, setting three evaluation dimensions. For foreign founders in medical devices, this signals tighter metrology oversight across the product lifecycle—affecting design, hospital use, and regulatory inspections.

China’s New Calibration Standard for Urine Meters

On 27 October 2026, China’s State Administration for Market Regulation (SAMR) released a new national metrology technical specification: the Calibration Specification for Urine Meters (the “Specification”). The move addresses a technical gap in the calibration of urine meters and strengthens metrology oversight in critical care—an area with direct implications for patient safety and for companies that manufacture or operate such devices in China.

For foreign founders building or running a medical device business in China, this development is a practical reminder that metrology requirements are part of the regulatory landscape. Understanding what the Specification covers—and how it links industry, hospitals, and regulators—can help you plan product design, quality control, and compliance.

Why Urine Meters Matter in Critical Care

Urine output is a core indicator for assessing a critically ill patient’s circulation and kidney function. Urine meters are bedside monitoring devices in intensive care units (ICUs), continuously collecting and recording patient urine data. Clinicians rely on this information to judge a patient’s condition and adjust treatment plans.

If the measurement is inaccurate, it can easily lead to a misjudgment of the patient’s condition and directly endanger the safety of critically ill patients. The Specification therefore focuses on ensuring that urine meters provide reliable, traceable data in real-world clinical settings.

Three Evaluation Dimensions

The Specification sets out three key metrological performance dimensions for evaluation:

• Alarm function: The device must be able to trigger audible and visual alarms when urine output is too high, too low, or when intermittent urine output exceeds a preset threshold. This helps medical staff quickly identify abnormal changes in a patient’s condition.
• Accuracy of total urine output indication: This assesses the device’s measurement performance for cumulative urine volume over a specified period, ensuring stable and reliable data during long-term continuous monitoring.
• Accuracy of intermittent urine output indication: This assesses the device’s measurement performance for cumulative urine volume within intermittent periods, ensuring that real-time displayed or output urine data is accurate and traceable, providing solid and credible data support for clinical diagnosis.

These dimensions are not merely technical checkboxes—they reflect the practical conditions under which urine meters operate in ICUs. For manufacturers, they offer a clear framework for product testing and quality control.

Connecting Industry, Hospitals, and Regulators

Once implemented, the Specification is designed to connect three links: industry, medical institutions, and metrology supervision.

Industry: Design and Factory Control

For manufacturers, the Specification guides companies to optimize product design in line with actual clinical conditions and to strengthen metrological performance control at the factory level. This means that foreign founders with manufacturing operations in China—or those sourcing from Chinese partners—should review whether their product design and出厂 (factory) testing align with the new evaluation dimensions.

Hospitals: Periodic Traceability

For the use side, the Specification guides medical institutions to establish a periodic traceability mechanism for urine meters, to reinforce the primary responsibility of medical units, and to carry out daily metrological control of in-use equipment. In practice, hospitals will need to ensure that their urine meters are calibrated and traceable on a regular basis.

Regulators: Inspections and Full-Chain Oversight

For the regulatory side, the Specification provides an authoritative technical basis for market regulation departments to conduct metrological supervision and inspection of medical equipment. It enables full-chain metrological supervision of critical care equipment—from production to clinical use.

Practical Implications for Foreign Founders

If you are a foreign founder involved in medical devices in China, this Specification is relevant whether you manufacture urine meters, import them, or operate them in a healthcare setting. Here are some practical steps to consider:

• Review product design and testing: Check whether your urine meters meet the three evaluation dimensions—alarm function, total urine output accuracy, and intermittent urine output accuracy. Ensure your design and factory testing reflect clinical conditions.
• Engage with calibration and traceability: If your devices are used in Chinese hospitals, work with your partners to establish periodic calibration and traceability processes in line with the Specification.
• Stay informed on metrology requirements: Metrology is a distinct regulatory layer alongside medical device registration. Keep track of national metrology technical specifications that may affect your product category.
• Coordinate with local partners: Whether through a wholly foreign-owned enterprise (WFOE), joint venture, or distributor, ensure that quality and metrology responsibilities are clearly allocated in contracts and operations.

The Specification does not introduce new registration procedures by itself, but it strengthens the technical basis for supervision. Foreign founders should treat it as part of a broader compliance strategy that includes product standards, quality management, and post-market surveillance.

What This Means for Market Access and Operations

China’s medical device market is regulated by multiple authorities, and metrology is one component. The new Specification signals that critical care devices will face closer scrutiny across their lifecycle—from design and manufacturing to hospital use and regulatory inspection. For foreign founders, this is an opportunity to demonstrate quality and build trust with Chinese healthcare providers.

It also underscores the importance of having a robust local presence or reliable partners who can handle calibration, maintenance, and regulatory communication. As the Specification is implemented, companies that proactively align with its requirements may find it easier to navigate inspections and hospital procurement processes.

Next Steps

Foreign founders should review their product portfolios and supply chains against the three evaluation dimensions. If you are planning to register a medical device company in China or already operate one, consider seeking local expertise on metrology compliance and quality control.
