Versatile & Easy to Use

One machine for multiple uses: Applicable to the latest national standard requirements, compatible with the standard of labor protection mask and daily protection mask

Easy switch: The whole instrument adopts special air circuit conversion elements to ensure that the two sets of pipeline systems for exhalation and inhalation are easily and quickly converted.

 

Selection of high-tech flow sensors

The flow sensor is highly sensitive and has a very small starting flow rate.

The flow sensor chip uses a thermal mass flow meter without temperature-pressure compensation, ensuring high-precision measurement of the sensor.

Multiple sensors are integrated on a single flow sensor chip, expanding the range of the sensor.

The flow sensor has high zero point stability and boasts high stability over the full range, high accuracy and repeatability, as well as low power consumption, low pressure loss and fast response time.

 

Superior micro-pressure sensor

Micro-piezometer sensor with two-wire system, high precision, good stability; explosion-proof design for safe and reliable use.

Micro piezometer sensor range, zero point external continuously adjustable, damping adjustable, no mechanical movable parts, low maintenance costs.

 

Specially designed data logger

Data logger with resolution 128 × 64 graphic dot matrix LCD, multi-language interface, easy to operate.

The data logger has 4M memory inside for measurement value recording.
