TM Data II
The TM data II utilizes the Tyndall effect for scattered-light measurements. Maximum intensity is achieved for particles with dimensions comparable to the wavelength of the light source. As this technique is insensitive towards coarse particles, no pre-separation is necessary. With no pump required, the instrument does not affect the aero-dynamic and concentration situation at the measurement site.
- Little maintenance requirements
- Very long battery operation time
- Intuitive operation
- Direct display of measurement results via touchscreen
