SJ-FCO4Dust measuring instrument calibration device Product Introduction
SJ-FCO4The dust measuring instrument calibration device is a test equipment used to simulate dust airflow environment, mainly composed of test wind tunnel, fan, dust generation device, dust collection device, control cabinet, air sampling device, electronic balance and other components. The device generates a circulating airflow with a certain wind speed in the wind tunnel through a fan, and injects particulate matter into the wind tunnel through a dust generating device to form a circulating flow of dusty air. The device adopts a precise mechanical structure and advanced computer control algorithms to stabilize the dust concentration in the wind tunnel around the set value, with high accuracy. This device generates the required dust airflow environment according to relevant national and industry standards, and can calibrate, calibrate, and detect measurement errors in dust measuring instruments such as dust concentration detectors, dust concentration sensors, and dust direct readers.

Product Features

The dust generator adopts a gear disc continuous feeding method, combined with a Venturi tube to achieve uniform dispersion of dust. The main shaft of the dust generator is driven by a stepper motor, and the dust generation speed is stable and controllable.

It can continuously and automatically adjust the dust emission, making the dust concentration in the wind tunnel highly stable and known.

The dust test wind tunnel is a circular structure with a uniform dispersion of dust inside. The wind speed and air volume inside the wind tunnel are stable and controllable.

The dusty airflow circulates in a closed wind tunnel, reducing environmental pollution and saving dust consumption.

All connections in the wind tunnel are sealed and equipped with enclosed dust collection devices to avoid environmental pollution.

The control cabinet is equipped with a color LCD display screen, which displays the real-time dust concentration and wind speed in the wind tunnel clearly and intuitively.

The dust concentration and wind speed can be set arbitrarily to meet different testing requirements.

The dust sampler has a split structure, which facilitates the replacement of filter membranes and panel operations.
