Mask Respirator Breathing Resistance Tester / Testing Machine / Equipment / Device / Apparatus / Measurement Instrument
It is used to measure the inspiratory resistance and expiratory resistance of respirators and masks under the specified conditions. Applicable to the national labor protection supplies inspection agency, mask manufacturers related inspection and inspection of ordinary masks, dust masks, medical masks, anti-fog mask products.
1. The instrument consists of an air source that can adjust the flow rate, a human head mold specified in the standard, two intubation systems for inhalation and exhalation, and a respiratory resistance measurement system.
2. The flow sensor has high sensitivity and has a very small starting flow.
3. The flow sensor chip uses a thermal mass flow meter, which does not require temperature and pressure compensation, ensuring high-precision measurement of the sensor. The range of the flow meter is 0 L / min ～ 100L / min, and the accuracy is ± 2%.
4. Multiple sensors are integrated on a single flow sensor chip, which greatly improves the range ratio of the sensor.
5. The zero point stability of the flow sensor is high, with full range and high stability, high accuracy over the full range, excellent repeatability, low power consumption, low pressure loss and fast response speed.
6. The data logger uses a graphic dot matrix LCD with a resolution of 128 × 64 and a full Chinese / English interface, which is easy to operate.
7, the data logger has 4M memory for measurement value recording.
