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

China’s market regulator has released a national metrology standard for urine meters, setting three evaluation dimensions that affect device design, hospital use, and regulatory oversight. Foreign founders in medical devices should understand the compliance implications for market entry and operations in China.

China’s New Calibration Standard for Urine Meters

On 27 October 2026, China’s State Administration for Market Regulation (SAMR) released a national metrology technical specification: the Calibration Specification for Urine Meters (the “Specification”). The move is intended to fill a technical gap in the calibration of urine meters in China and to strengthen metrological supervision in critical-care medical settings. For foreign founders developing or selling medical devices in China, the Specification signals how regulators will assess certain bedside monitoring equipment and what companies should prepare for.

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 essential bedside monitoring devices in intensive care units (ICUs), continuously collecting and recording patient urine data. Doctors rely on these readings to judge a patient’s condition and adjust treatment plans. If measurement is inaccurate, it can easily lead to 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 data in clinical use, particularly in continuous monitoring scenarios common in ICUs.

Three Evaluation Dimensions Defined by the Specification

The Specification sets out three key dimensions for evaluating the metrological characteristics of urine meters:

• Alarm function: The device must be able to trigger timely audible and visual alarms when urine output is too high, too low, or when intermittent urine output exceeds preset thresholds. 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. It ensures that data remains stable and reliable during long-term continuous monitoring.
• Accuracy of intermittent urine output indication: This assesses the device’s measurement performance for cumulative urine volume during intermittent periods. It ensures that real-time displayed or output urine data is accurate and traceable, providing solid and credible data support for clinical diagnosis.

Impact Across Industry, Healthcare Providers, and Regulators

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

• Industry side: Manufacturers are guided to optimize product design according to actual clinical conditions and to strengthen metrological performance control at the factory level.
• User side: Medical institutions are guided to establish periodic traceability mechanisms for urine meters, to reinforce the primary responsibility of medical units, and to manage daily metrological control of in-use equipment.
• Regulatory side: The Specification provides an authoritative technical basis for market regulators to conduct metrological supervision and inspection of medical equipment, enabling full-chain metrological supervision of critical-care equipment from production to clinical use.

Practical Implications for Foreign Founders

For foreign founders registering or operating a company in China, the Specification has several practical implications, particularly for those in the medical device sector.

1. Product Design and Manufacturing

If your company manufactures urine meters or similar critical-care monitoring devices for the Chinese market, you should review your product design against the three evaluation dimensions. Ensure that alarm functions meet the specified triggering conditions for high, low, and intermittent urine output thresholds. Verify that total and intermittent urine output measurements are accurate and traceable over the intended use periods. Strengthen factory-level metrological performance controls to align with the Specification’s expectations.

2. Hospital Use and Traceability

Medical institutions in China will be guided to establish periodic traceability mechanisms for urine meters. If your company supplies devices to Chinese hospitals, you may need to support calibration and traceability requirements, including providing documentation or services that help hospitals comply with their metrological management responsibilities.

3. Regulatory Inspections

The Specification gives market regulators a technical basis for inspecting medical equipment. Foreign-invested companies should be prepared for potential metrological supervision and inspections, and should maintain records demonstrating conformity with the Specification’s requirements.

4. Market Access and Compliance Planning

While the Specification is a metrology technical document, it forms part of the broader regulatory environment for medical devices in China. Foreign founders should consider how it interacts with other requirements, such as product registration and quality management. Early planning can help avoid delays and ensure that devices meet both clinical and regulatory expectations.

Next Steps for Foreign Founders

Foreign founders should monitor the implementation of the Specification and assess whether their products or operations are affected. Companies in the medical device sector, particularly those involved in critical-care monitoring, should review their design, manufacturing, and post-market processes to align with the new requirements. Engaging with local metrology and regulatory experts can help clarify specific obligations.
