GBPI GBN702 Respiratory resistance tester

https://www.gbpitester.com


Application: ,

The respiratory resistance tester is suitable for determining the inhalation
resistance and exhalation resistance of respirators and mask protective products
under specified conditions, and for the related testing and inspection of common
mask products by manufacturers of national labor protection article inspection
agencies.

Standard:

EN149

Features:

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.
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 points of the micromanometer sensor are continuously
adjustable, the damping is adjustable, there is no mechanical moving part, and the
maintenance workload is small.
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. Applicable to the latest national standard requirements, compatible with labor
protection protective masks and daily protective mask standards
