Why HOLFENRY?
We are an all-round enterprise focusing on the design, manufacture and sales of home health monitoring products. We are committed to providing customers with easy-to-use, convenient devices — home adult pulse oximeters, children's pulse oximeters, handheld pulse oximeters, rechargeable noise-cancelling hearing aids, pocket hearing amplifiers and blood pressure monitors.
We have a professional quality-control system and a highly integrated production mode. Based on customer-demand identification, we strictly follow standardised operating procedures, accurately use operating tools, standardise operating methods and production records, and control every production and inspection link. Real-time quality measurement and supervision inspections keep product quality on target.
