FeNO Detector Calibrator

FeNO testing is a new medical technique used to assist in the diagnosis of asthma. Nitric oxide is a biomarker of asthma, and by measuring the amount of nitric oxide in a patient's exhaled breath, it can assess the level of lung inflammation and help diagnose asthma. In addition, FeNO detection is also widely used in the diagnosis and monitoring of other respiratory diseases, such as chronic cough and COPD.

FeNO testing has been used in most physical examination centers and outpatient clinics, with a large amount and a wide range, which is related to people's health and involves thousands of households.

FeNO values in healthy people are within a certain range, higher or lower than this range will cause health warnings.

It is of great significance to carry out the calibration work of FeNO detector to ensure the accuracy and reliability of its measured values. The accuracy of FeNO detector can improve the diagnostic accuracy of suspected asthma patients and avoid misdiagnosis and treatment. Can improve the effectiveness of patient care through a better understanding of individual conditions; It can improve the treatment effect of patients and reduce the risk of aggravation and admission. It can also reduce inappropriate prescribing, including corticosteroid prescribing; It would also reduce the number of inappropriate referrals to secondary care clinics.

EUCA Technology Co., Ltd. cooperated with experts from the Chinese Academy of Measurement Sciences to develop a calibration device for FeNO detector that simulates human exhalation. Through scientific, accurate and reliable dynamic gas distribution technology, high humidity generation technology and precision temperature control technology, nitric oxide can be accurately traced under the condition of human exhalation temperature and humidity. Provide accurate and reliable solutions for the calibration of FeNO detectors.

 This is China's new contribution to the international metrology community!
