Description
The FeNO test is a new medical technology used to aid in the diagnosis of asthma. Nitric oxide is a biomarker for asthma. By measuring the nitric oxide content of a patient's exhaled breath, the level of inflammation in the lungs can be assessed to help diagnose asthma. In addition, FeNO test is also widely used in the diagnosis and monitoring of other respiratory diseases, such as chronic cough, COPD, etc. FeNO test has been applied in most of the medical checkup centers and outpatient clinics, which is a large quantity and concerns the people's health and involves thousands of families.
The FeNO - CaNO Breath Nitric Oxide Calibration Device is used to calibrate the FeNO tester by simulating human breath. This ensures that the FeNO tester is accurate and reliable in assisting the diagnostic process, and provides a basis for the selection of diagnostic and therapeutic programs for patients.
FeNO detector calibration device uses scientific, accurate and reliable dynamic gas distribution technology, high humidity generation technology, precision temperature control technology, simulated human breath temperature and humidity conditions of nitric oxide accurate traceability, the first to provide accurate and reliable solutions for the calibration of FeNO detector.
