Filter holder FD-05D

The filter holder is designed to install an aerosol filter of the AFA type in it. It is used in sampling systems of gas-aerosol media at radiation-hazardous and other production facilities.

Application range: 1.8 ... 55.0 m/s Alarm threshold setting range: wind speed from 12 to 40 m/s The range of setting alarm thresholds in time is from 2 to 5 seconds. Accuracy characteristics: PG±(0.5+0.05V) m/s The average service life is at least 8 years. Application conditions: wind speed sensor from -60C to +50C

It is designed to measure sound pressure in the air and is used in noise measuring equipment as a measuring transducer of infrasound, sound and ultrasonic pressure.

The drip collector is designed to remove droplet moisture when sampling air from indoor ventilation systems and is installed in gas aerosol sampling systems. Purpose: removal of droplet moisture from the selected air sample; accumulation of droplet moisture; indication of the level of accumulated moisture; draining the accumulated moisture.

It is designed to measure sound pressure in the air and is used in noise measuring equipment as a measuring transducer of infrasound, sound and ultrasonic pressure.
