GB19083-2010 High Sensitivity Flow Sensor Mask Breathing Gas
Resistance Tester
Overview:
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.
Technical parameters:
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 interface, which is easy to operate.
7, the data logger has 4M memory for measurement value recording.
8. The micromanometer sensor uses a two-wire system, with high
accuracy and good stability; it is safe and reliable to use an
explosion-proof design.
9. The range and zero point of the micromanometer sensor are
continuously adjustable, the damping is adjustable, there is no
mechanical moving part, and the maintenance workload is small. The
micro-pressure measurement range is -1000Pa to 1000Pa, and the
accuracy is 1Pa.
10. The whole instrument adopts special gas path conversion
elements, which ensures the convenient and fast conversion of the
two-pipe system of exhalation and inhalation.
11.The suction volume of the suction pump is not less than 40L /
min ~ 100L / min
12. Ventilation volume is constant at (85 ± 1) L / min
13. Power supply: AC220V, 50Hz

Maintenance:
1. Do not carry it by the bottom of the control box during
transportation to avoid being crushed.
2. Please wipe the electroplated part with oil to prevent rust and
keep bright.
3. After the test, please wipe the machine clean, and regularly oil
the active fulcrum to increase its service life and sensitivity.
( The lubricating oil can be mixed with butter and a little engine
oil)
4. Please wipe the panel (control box or display) with a dry cloth
to prevent it from getting wet, so as not to damage the IC
electronic parts.
5. Please place all fixtures and joint accessories properly, and
wipe off the anti-rust oil to prevent rust.
6. After the machine is transported and placed, the foundation and
the level must be fixed steadily.
7. Please input power as indicated. (Note that the phase of the
input power supply must be correct, otherwise leakage will occur)
8. Ground wire Please perform ground output in accordance with
specifications to avoid danger of leakage and signal interference.
9. Do not pull out the plug during work.
10. Please operate and maintain by professional personnel. In case
of major problems, please inform our maintenance department to
dispatch personnel to handle it. Do not dismantle parts by yourself
to avoid causing major losses.
