Met One Instruments Powered by Acoem products

The ES-405 is a near reference air quality sensor designed to provide accurate real-time measurements of TSP*, PM₁₀, PM₄, PM_2.5, and PM₁ particulate concentrations simultaneously. It reports these five key particulate concentrations in both indoor and outdoor environments. The rugged weatherproof enclosure allows use in the harshest environments for reliable continuous outdoor operation, and the inlet heater reduces moisture-related measurement error. The sensor incorporates sheath air to prevent particles from contaminating the internal optics of the sensor. The ES-405 can be wall-mounted or installed on a vertical mast.

The Aerocet 380 is a Nephelometer developed by Met One Instruments Powered by Acoem that offers real-time airborne TSP (total suspended particulate) concentration levels using the principle of forward-laser light scatter. This instrument is ideal for sampling in any indoor workplace or public place environment with optional separators to monitor PM1, PM2.5, or PM10.

The Aerocet 532 particle monitor has been optimized in functionality and ease of use with a 2.8″ TFT full-color LCD display, making accurate measurement readings and operation more effortless than ever. Measuring both particle mass and particle count, this full-featured particle monitor is the perfect addition to any indoor air quality expert’s tool kit. The Aerocet 532 simultaneously measures and records PM1, PM2.5, PM4, PM7, PM10, and total suspended particulate (TSP). Measurements are rapidly computed and totaled in as little as 60 seconds, recorded using an advanced profile algorithm. In addition to making mass measurements, the Aerocet 532 contains an 8-channel particle counter with a calibrated range of 0.3 to 10 microns.
