Used PMS LASAIR II #293760597 for sale

PMS LASAIR II is an aerosol particle counter designed by Particle Measuring Systems (PMS) used to measure and monitor particulate matter (PM). It is capable of detecting a wide range of aerosol particle sizes from 0.1 μm in diameter up to 20 μm. It can measure in both indoor and outdoor environments and is particularly useful in monitoring industrial environmental standards and public health warnings. The instrument utilizes a single laser diode and two optical detectors to measure particle mass and number size ranges. The single laser diode uses Laser-Induced-Incandescence (LII) to measure the size of particles in the 0.1 - 1.0 μm size range. The laser passes through the sample and the light scattered by particles is collected by the two optical detectors. This scattered signal is converted to a number concentration and mass concentration for each size range. The instrument also incorporates an optimized air inlet design which minimizes the impact of external factors such as wind and temperature on the sample stream entering the instrument. Furthermore, the inlet design also makes it effective at measuring a range of particles including those which are electrostatically charged, non-spherical and super absorbent. LASAIR II also has a low instrument background noise level, meaning that it can accurately measure low concentration samples. It is also capable of providing real-time output of data for up to 24 hours, meaning it can be used for extended sampling periods. It also incorporates several features that make it easy to use, such as on-screen viewing of sample conditions, intuitive menu navigation and a user-friendly, integrated touchscreen interface. Overall, PMS LASAIR II is a reliable, high performance aerosol particle counter capable of providing accurate, real-time output of data for particulate matter monitoring. It is well suited for use in a range of indoor and outdoor environments and provides an effective means of monitoring industrial environmental standards and public health warnings.
