Building occupants deserve better indoor environmental conditions in order to grow and thrive.
Our company provides a precise and confident solution to building management experts and occupants who want to achieve their goals with the AIRCARE Monitor.

Particles Plus offers a line of advanced-technology particle counters, air quality monitors, and sensors. As the most vertically integrated particle counter manufacturer and technology licensing company in the industry, Particles Plus engineers and manufactures its own sensor technology. We deliver products with superior performance, extended features, accuracy, reliability and value.

  Show Specials

  • The Particles Plus® 8301-AQM1 and 8301-AQM2 Series Handheld Particle Counter and Environmental Monitor measures 0.3 to 25 µm particles with mass concentration and stores indoor air quality measurements of temperature, relative humidity, CO2, and TVOC in the 8301-AQM2. This instrument is the most versatile handheld Air Monitor available, with advanced power management and the industry’s first sleep mode, allowing for battery operation of periods that can exceed a month on a single charge. The AQM Series can be used as a stand-alone battery operated instrument or it can be easily integrated into a building automation and facility monitoring system via Ethernet, USB or (optional) Wireless 802.11 b/g, RS485 or RS232 connection.

  Press Releases

  • Particles Plus instruments were used during the research into In-Situ Elemental Composition Analysis of Large Inhalable Aerosol Using Laser Induced Breakdown Spectroscopy at Colorado State University. The paper was presented by Professor Azer Yalin et al., 2022.

    The researchers used Particles Plus optical scattering sensor technology to measure particles with an aerodynamic diameter exceeding 20 μm.

    Aerosol researchers have primarily focused on detecting small (below 10 μm) particles due to their presence in almost all environments and the health impact associated with their inhalation. However, inhalable particles larger than 20 μm are also present in many industrial environments such as grinding, computer numerical control (CNC) machining, lead smelting, and battery manufacturing. If these inhaled particles are toxic to health (e.g., lead, nickel, or cadmium), then it is important to identify the presence of these elements to limit exposure.

    The main purpose of the paper was the development of a direct-reading particle sizer (DRPS) that uses optical scattering signals and laser-induced breakdown spectroscopy (LIBS) to obtain direct time-resolved measurements of the aerodynamic diameter and elemental composition of large (∼20–100+ μm) airborne particles.

    Particles Plus OEM optical counters are advanced instruments that offer flexibility and precision to researchers and product developers that want to collect high-quality particulate data.
