On November 5, 2025, Xi'an Yingrun Environmental Protection Technology Group Co., Ltd. (referred to as "Yingrun Group") officially announced that its independently developed and producedERUN-S series water quality testing instrumentSuccessfully passed the EURoHS（Restriction of Hazardous Substances）Environmental certification. This achievement marks that the products of Yingrun Group have not only reached international standards in performance, but alsoGreen Manufacturing and Environmental FriendlinessObtained international recognition in this regard.
What is RoHS certification? Why is it so important?
RoHS is the European Union'sDirective 2011/65/EU(Later on)2015/863/EU 修正）The mandatory environmental standards proposed are called the "Directive on Restricting the Use of Certain Hazardous Substances in Electronic and Electrical Equipment". This standard applies to lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (Cr6+), polybrominated biphenyls (PBB), and polybrominated diphenyl ethers (PBDE), among others10 harmful substancesThe content has been strictly limited.
The ERUN-S series has passed this certification, which means that it meets the highest requirements of the European Union for environmental protection, sustainability, and consumer safety in the production process, ensuring that the products are exported to Europe, the Americas, and other countries and regions that highly value environmental standards,No additional testing or compliance barriers required.
What international standard tests has Yingrun Group passed?
This certification covers the following International Electrotechnical Commission (IEC) standard projects, including quantitative analysis, extraction methods, and detection sensitivity of harmful substances in materials:
| Standard Number | Standard Name | Release Year |
|---|---|---|
| IEC 62321-3-1 | Sample preparation and screening testing | 2013 |
| IEC 62321-4 | Quantitative analysis of lead, cadmium, mercury, and hexavalent chromium | 2013 + AMD1:2017 |
| IEC 62321-5 | PBB and PBDE detection in polymers and electronic materials | 2013 |
| IEC 62321-7-1 | Hexavalent chromium detection (color method) | 2015 |
| IEC 62321-7-2 | Hexavalent chromium detection (electrochemical method) | 2017 |
| IEC 62321-6 | Mercury analysis (cold atomic absorption method) | 2015 |
| IEC 62321-8 | Phthalates detection | 2017 |
Through the above standards, the ERUN-S series instruments have reached international standards in material selection, assembly processes, and electronic component safety.
What does RoHS certification mean for Yingrun Group?
RoHS certification is not only a technical qualification, but also an important milestone for Yingrun Group to practice the concept of "environmentally friendly manufacturing and technological innovation".
✅Global market accessRoHS is an important passport to enter the European Union and many international markets;
🌱Green supply chain guaranteeAll electronic components and materials are sourced from suppliers that meet environmental standards;
💡Brand internationalization enhancementMarking that the water quality monitoring equipment of Yingrun Group has reached the international environmental protection manufacturing system;
🔧Product reliability enhancementReduce the risk of harmful substance migration, extend equipment lifespan and stability.
Ding Zhijie, General Manager of Yingrun Group, said at the press conference: "Passing RoHS certification is not only a recognition of our production system, but also another leap forward for Yingrun in promoting continuous innovation in global environmental testing technology. ”
Environmental Protection and Technology Dual Drive of ERUN-S Series Water Quality Detector
The ERUN-S series is a high-performance water quality testing platform launched by Yingrun Group for the fields of industry, water treatment, environmental monitoring, and scientific research laboratories.
Its product features include:
High sensitivity sensor with a detection accuracy of 0.01 mg/L;
Modular design, easy to replace and upgrade quickly;
Low power circuit design reduces carbon emissions by about 20%;
Support cloud remote monitoring and intelligent calibration functions.
With the support of RoHS certification, the ERUN-S series is not only widely used in the Chinese market, but also exported to many countries with strict environmental standards such as Germany, Italy, and Japan, becoming one of the representative products of "Made in China" going global.
The Sustainable Development Blueprint of Yingrun Group
As a well-known domestic manufacturer of online water quality monitoring equipment, Yingrun Group has always adhered to the development concept of "technology-based, green first". The company has currently passedISO 9001 Quality Management System Certification、ISO 14001 Environmental Management System Certification、CE CertificationWaiting for multiple international qualifications.
In the future, Yingrun Group will continue to increase its investment inEnvironmentally friendly materials, energy-saving design, and circular manufacturingResearch and development investment in various fields will help promote the sustainable development of the global water environment monitoring industry.
The ERUN-S series water quality detector of Yingrun Group has obtained RoHS certification, which is not only a comprehensive improvement of the company's own quality system, but also an important symbol of China's water quality monitoring equipment moving towards high standards, greenness, and intelligence on the international stage. Yingrun Group will continue to promote the upgrading of the environmental testing industry through technological innovation, and safeguard the future of global clean water resources.
