GRIMM 1152
Isokinetic sampling set
Special tube in tube probe for Grimm aerosol spectrometers for correct determination of the particle size distribution and dust mass fractions in gases. Suitable for all models with 1.2 l/min sample volume flow.
Functionality: Isokinetics, air recirculation
Features
- Isokinetic and isoaxial sampling up to velocities of 25 m/s
- Four selectable inlet nozzles
- Exhaust air recirculation
- Markings for exact positioning of the nozzle in the duct
- Color spots for an isoaxial positioning of the inlet nozzle in the sampling air
- Quick fix mechanic for easy use
- Suitable for cross sections from 16 cm upwards
- Straight extension for cross sections up to 100 cm
Benefits
- No particle cut-off
- Easy-to-use
- Adapt your measurement instrument to difficult sources
- Stainless steel
Applications
- Lossless measurements at higher wind speeds
- Lossless measurements at varying air pressures
