I'm interested in obtaining information regarding the ISO certification for your pulse oximeter. Can you please provide details about the current certification status, including any relevant documents or links? Additionally, I'd like to know more about the certification process your factory follows, as well as any quality standards that are in place for your products. This information is crucial for our purchasing decisions, so your prompt response would be greatly appreciated.
