A leading manufacturer of medical diagnostic devices, specializing in pulse oximeters, blood pressure monitors, patient monitors, and ultrasound equipment for home and clinical use.
Contec Medical Systems Co., Ltd. (Contec) is a global manufacturer specializing in medical equipment and healthcare devices. Established in 1996, the company is renowned for producing accessible and reliable diagnostic tools, including the popular CMS50 series of fingertip pulse oximeters, ambulatory blood pressure monitors (ABPM), ECG workstations, and pocket fetal dopplers.
While the Contec name is primarily associated with its widespread medical solutions used in hospitals and home care, the brand identifier also encompasses industrial machinery (such as floor strippers from Contec Maschinenbau) and cycling components in certain markets. However, the majority of user manuals and support inquiries relate to Contec's extensive line of health monitoring technology, designed to provide professional-grade data for patient care.

Common questions about manuals, registration, and support for this brand.
Software for data management (such as SpO2 Assistant) is typically included on a mini-CD with the product. Updated versions may be found on the official Contec Medical Systems website under the download or support interface.
The 'Sensor Off' or 'Sensor Fault' message indicates that the probe is disconnected, damaged, or not properly positioned on the finger or body. Check the connection and probe integrity.
Use a soft cloth dampened with 70% isopropyl alcohol or a 5% soapy water solution. Wipe the sensor and cable surfaces gently. Do not immerse the device in liquid.
Many Contec handheld monitors and wrist oximeters are designed for continuous monitoring or overnight recording. However, standard fingertip spot-check models are not intended for long-term continuous use.
Most Contec home-use devices are calibrated at the factory. For professional environments, it is recommended to inspect the device periodically (e.g., weekly) and check for accuracy, though re-calibration is often not user-serviceable without specific equipment.
