DiSCmini promo until next 20th December
We are glad to inform you that we are offering with every DiSCmini purchase the first service maintenance and calibration for free. This promotion is valid for every new testo DiSCmini purchased until 20th December 2016.
The Diffusion Size Classifier Miniature DiSCmini is a handheld sensor for the measurement of nanoparticle number, average diameter and lung-deposited surface area LDSA with a time resolution of up to 1 second (1 Hz). The measuring principle is based on electrical charging of the aerosols. The small size of the testo DiSCmini makes the instrument particularly suitable for personal carry-on measurement campaigns. The instrument is battery powered with a lifetime of up to 8 hours; data can be recorded on a memory card, and transferred to an external computer via USB cable.
Testo DiSCmini is particularly efficient for personal exposure monitoring in particle-loaded work space with toxic air contaminants such as diesel soot, welding fumes, or industrial nanomaterial. Testo DiSCmini detects particles ranging in size from 10 to about 700 nm, while the modal value should lie below 300 nm. The concentration range is from about 1'000 to over 1'000'000 particles per cubic centimeter. The accuracy of the measurement depends on the shape of the particle size distribution and number concentration, and is usually around 20% compared to a reference CPC.
Unlike other instruments testo DiSCmini needs neither working liquid of any kind nor radioactive sources. Therefore, it can be operated in any position and over extended periods without requiring a liquid refill. Typical applications include the determination of personal exposure in particle-loaded works or in vulnerable groups (asthmatics, COPD patients). The development of large area survey grids of ambient air is becoming possible. The high time resolution of 1 Hz enables the instrument to monitor rapid changes in the aerosol. This feature is particularly interesting for local or defined sources of particle generation. The equipment is designed for situations and applications where quick and easy access to particle number concentration and average diameter is required.
