Audited Supplier The tester introduction
Mask breathing resistance tester is used to determine the respirator and mask type protective equipment in the specified conditions of the inspiratory resistance and expiratory resistance. Applicable to the national labor protective equipment inspection agencies, mask manufacturers of ordinary masks, dust masks, medical masks, anti-haze mask products for the relevant testing and inspection.
Equipment use
Mask breathing resistance tester is used to determine the respirator and mask-type protective equipment under the specified conditions of inspiratory resistance and expiratory resistance. Applicable to the national labor protective equipment inspection agencies, mask manufacturers of ordinary masks, dust masks, medical masks, anti-haze mask products for the relevant testing and inspection.
The technical indicators
1, the instrument consists of the air source that can adjust the flow, the standard prescribed human head model, inhalation and exhalation two sets of piping system, respiratory resistance measurement system, etc.
2, the flow sensor is highly sensitive, with a very small starting flow.
3, flow sensor chip using thermal mass flow meter, no temperature pressure compensation, to ensure the high accuracy of the sensor measurement. The flow meter range is 0 L/min ~ 100L/min, the accuracy is ± 2%.
4,Multiple sensors are integrated on a single flow sensor chip, which makes the range ratio of the sensor greatly improved.
5,The flow sensor has high stability of zero point, high stability of full range, high accuracy of full range and excellent repeatability, low power consumption, low pressure loss and fast response time.
6,The data logger adopts 128×64 resolution graphic dot matrix LCD, full Chinese interface, easy to operate.
7,The data logger has 4M memory for measurement value recording.
8, the micro piezometer sensor using two-wire system, high precision, good stability; explosion-proof design for safe and reliable use.
9, micro piezometer sensor range, zero point external continuously adjustable, damping adjustable, no mechanical moving parts, less maintenance workload. Micropiezometer range of -1000Pa ~ 1000Pa, the accuracy of 1Pa.
10,The whole instrument adopts special gas circuit conversion components to ensure that the exhalation and inhalation of the two sets of piping system conversion is convenient and fast.
11,Pump pumping capacity 40L/min~100L/min
12,The ventilation volume is constant (85±1)L/min
13,Power supply: AC220V, 50Hz
14, applicable to the latest national standard requirements, compatible with labor protection protective masks and daily protective mask standards
