The microAeth® Model AE51 is the world's first ever real-time, pocket-sized Black Carbon aerosol monitor. This palm-size instrument is small enough to be worn by a person in order to measure the real-time concentration of black carbon which a person may be exposed to. The microAeth incorporates the same Aethalometer® measurement technology which has been used worldwide for over 25 years, all in a package that can fit in your pocket.
The instrument can operate continuously for up to 24 hours on a single battery charge and can be externally powered by the included wall power adapter, or an additional external battery option for longer run times. The air sample is collected on T60 (Teflon coated glass fiber) filter media, and analyzed in real time. The filter media is housed in an easy to replace filter strip for simple handling in the field.
The microAeth has been used to take measurements of cookstoves, tobacco smoke exposure as well as on planes, trains, bicycles, even on weather balloons measuring vertical profiles of Black Carbon in the atmosphere. This versatile instrument can be used to easily measure Black Carbon everywhere.
The Thermo Scientific Personal DataRAM PDR-1500 is a personal aerosol instrument that offers benchtop performance. A fully integrated, active, volumetrically controlled, personal sampling instrument with greater precision, increased capabilities, and decreased size and weight in an easy to use package. See also the ADR which is designed for continuous outdoor montiroing of dust.
The next step in miniaturisation of UV-based ozone monitors by developing the Personal Ozone Monitor or "POM". The POM has dimensions of 4 x 3 x 1.5 inches and weighs only 0.75 lb (340 g). It has a built in GPS so that ozone measurements may be logged continuously along with geographic location. By folding the optical path in the shape of a "U", it was possible to achieve the same path length in the POM as in the Models 202, 205 and 106-L and thus have similar precision and accuracy (~2 ppb).
