EEPS can be retrofitted to PTT! By reducing the number of moving parts inside the device, we achieve low maintenance requirements.
The "3095 (3098 PTT PLUS 3090 EEPS(TM))" is a particle size distribution measurement device that supports reduced loss rates and sampling at high back pressure. The 3090 EEPS measures the particle size distribution of PM emitted from engines in real-time. The 3098 PTT consists of a dilution mechanism using PTT and a volatile particle removal mechanism known as CS. By adopting the Porous Tube Thermodiluter dilution mechanism, it reduces particle loss within the device. 【Features】 ■ When combined with EEPS, it acquires number concentration and mass concentration particle size distribution in real-time (10 Hz). ■ Equipped with a volatile particle removal device (Catalytic Stripper) that is being considered for introduction in the next European emission regulations under the PMP method. ■ Reduction of particle loss due to thermophoresis and diffusion. ■ New software allows for control of the dilution ratio of PTT and EEPS. ■ Calibration of PPT only requires replacing the modular flow controller. ■ EEPS can be retrofitted to PTT. *For more details, please refer to the PDF materials or feel free to contact us.
