TSI 3333-10 Aerosol Diluter

 

Monitoring ambient particle concentrations at pollution hot spots such as major traffic junctions, motorways, airports, or seaports can be challenging for Condensation Particle Counters (CPCs). The high concentrations of ultrafine particles can frequently exceed the maximum concentration limit of the CPC; this lowers the data quality, and can necessitate more frequent maintenance. The Aerosol Diluter lowers the particle concentration 10-fold by diluting the aerosol sample with a constant controlled flow of internally supplied filtered air. It is designed to enable continuous monitoring of ultrafine particle concentrations with the CPC 3750 or 3750-CEN.

Description

Product Details

Aerosol flow through the diluter is controlled by the attached CPC. The dilution air flow is controlled to produce a very stable dilution ratio of 10:1. The dilution flow and the sampled aerosol flow are blended in a helical mixer that has low particle losses. The dilution flow and ratio are recorded by the CPC when the two are connected via USB.

Features

  • Designed to work at the flow rate of the CPC 3750 and 3750-CEN (1.0 L/min); aerosol flow rate is provided by the attached CPC.
  • Dilution air is monitored by an internal mass flowmeter and generated by an internal blower.
  • Electronic communication to CPC (3750 and 3750-CEN): Diluter reads calibrated aerosol flow from the CPC, maintains a fixed dilution ratio of 10:1, and communicates parameters (diluter flow, ratio, and others) to the CPC

Applications

  • High particle concentration measurement
