[New high-capacity sampling device for controlling air dust content].

The construction of a new high-capacity sample taking device, designed for dust pollution control, and furnished with an electric aspirator is described. The device can be used in weight analyses of dust pollution in the air of working rooms and atmosphere alike. The basic feature of the apparatus is the so-called sample taking head which fulfils the functions of measurer and regulator of the capacity within 50-200 dm3/min limits. The measurement filters are made of FPP-15 material with dimeter measuring 80 mm. Sample taking using the above device is conducted in compliance with the requirements of dust control standards adopted in this country.
