Respiratory Resistance Tester
Standards:
· GB/T 2626-2006 Respiratory protective equipment -- non-powered air-purifying particle respirator - 6.5 6.6 · GB/T 32610-2016 Mask technical specification of daily
Applications:
The respiratory resistance tester is used to determine the inspiratory and expiratory resistance of respirator and mask protective equipment under specified conditions.
Product Information:
It applies to do the relevant detection and inspection for the national labor protection equipment inspection agencies, masks manufacturers of ordinary masks, dust masks, medical masks, and anti-haze masks products.
Technical Parameters
·Flowmeter range is 0 L / min -100L / min, accuracy is ± 2%;
·Micro-pressure gauge range is 0-1000Pa, accuracy is 1Pa;
·Suction pump pumping capacity is not less than 100L / min;
·The ventilation capacity was constant at (85 ± 1) L / min;
·Power supply: AC220V, 50Hz
Feature
·The instrument consists of gas source that can regulates the flow, standard specifies of small human head mold, inspiratory and expiratory line system, a respiratory resistance measurement system, and so on.
·Flow sensor has high sensitivity and minimal start flow. Flow
sensor chip uses thermal mass flowmeter, no temperature and
pressure compensation to ensure the sensor's high-precision measurement.
·Multiple sensors are integrated on a single flow sensor chip, resulting in the sensor range greatly improved.
·The zero stability of the flow sensor is high, with full range of high stability, with full range of high accuracy and excellent in repeatability, with low power consumption, low voltage loss and fast response characteristics.
·Data recorder uses graphics dot matrix LCD with resolution of 128 × 64, entire Chinese interface, easy to operate.
·There are 4M memory in the data recorder for record the measured value.
·Micro-pressure gauge sensor adopts two-wire system, has high precision, good stability; And adopts anti-explosion design for safe and reliable.
·Micro-pressure gauge sensor range, zero external continuously to adjustable, damping adjustable, no mechanical moving parts, less maintenance work.
·Adopting special air-switching components to ensure that the two sets of inspiratory and expiratory piping system replacement is quick and easy.
·Digital show the respiratory resistance, with zero calibration, accuracy calibration and over-range alarm function.
·Equipped with a silent air compressor and air filter to ensure that the test environment is quiet and tidy.
·Meeting with the latest national standards, compatible with labor and daily protective masks.
