Product features
Tqd-03 air resistance and respiratory resistance tester is used to measure the inspiratory and expiratory resistance of masks under specified conditions, and also can be used to measure the air penetration resistance of textiles, cotton floc, space cotton, masks, etc. It is applicable to the inspection and testing of mask products by mask manufacturers and national labor protection equipment inspection institutions
The product feature
· 7-inch color touch screen, easy to operate
· the instrument consists of an air source that can adjust the flow rate, a human head mold specified in the standard, an inhaling and exhaling double casing system, and an airflow resistance measurement system.
· high sensitivity of flow sensor, with minimal initial flow
· the flow sensor chip adopts thermal mass flowmeter, without temperature and pressure compensation, ensuring the high precision measurement of the sensor. The accuracy is ±2%.
· multiple sensors are assembled on a single flow sensor chip, which greatly improves the range ratio of the sensor
· the flow sensor has high zero stability, high accuracy in full range, excellent repeatability, low power consumption, low voltage loss and fast response speed.
· the micro-manometer sensor adopts two-wire system with high precision and good stability; The use of explosion-proof design is safe and reliable.
