testo 350 Portable Emission Analyzer

testo 350 Portable Emission Analyzer



 Test up to six gases simultaneously, or swap sensors out:

[O2], [CO, COlow], [NO, NOlow, NO2] , [SO2, H2S],  [CO2 (NIDIR)], [CH (total hydrocarbons)]


USEPA ETV Verfication & the testo 350 M/XL

The acceptance of portable electrochemical-based analyzers by state and federal environmental agencies has been overwhelming over the past decade. Numerous third party organizations have tested and evaluated the technology and found that not only does it satisfy the accuracy requirements of many compliance-testing programs, but also it offers a more affordable and better time managed solution. Coupled with great cross utilization capability that can identify improvements in the combustion, process and product quality, makes the testo 350 M/XL a truly valuable asset to any organization.

testo DiSCmini 奈米微粒數目監測儀

The all new testo DiSCmini is a portable sensor for the measurement of particle number and average diameter, based on the electrical charging of the aerosols. The small size of the testo DiSCmini handheld makes the instrument particularly suitable for personal carry-on measurement campaigns.

It was designed with ease of use in mind - it is truly handheld, operates without working fluids or radioactive sources, operates in any orientation and on-the-go. It can be used for personal exposure monitoring or quick walk-through surveys of an area of interest, such as a workplace, or an urban area with heavy traffic. Its concentration detection limit is ideally suited for typical ambient particle concentrations. The miniDiSC is less accurate than traditional aerosol instruments such as CPC (condensation particle counter) and SMPS (scanning mobility particle sizer), available from e.g. TSI or Grimm, but this is often more than compensated for by its smaller size and easier handling. In general, measured concentrations and average diameters agree to within 30% with CPC and SMPS. Compared to its main competitor (the handheld CPC) it is smaller, easier to use and also delivers an average particle diameter and lung-deposited surface area and not only the particle number concentration. The handheld CPC is better suited when only number concentration is of interest, and when particle concentrations are below 1'000 per ccm.

Applications
