Met One ES-405 Remote Particulate Profiler
MetOne ES-405 Remote Particulate Profiler $180 $420 $1,200

The ES-405 is a near reference air quality sensor designed to provide accurate real time measurements of PM10, PM4, PM2.5, and PM1 particulate concentrations simultaneously.

Met One’s ES-405 reports four key particulate concentrations in both indoor and outdoor environments, and is equipped with a rugged, weatherproof enclosure that permits use in the toughest environments for reliable, continuous operation. The inlet heater reduces moisture-related measurement error, while the sensor incorporates sheath air to prevent particles from contaminating the internal optics of the sensor. Mounting options include installation on a vertical mast or wall-mount.

All ES-405 Particulate Profilers are manufactured at an ISO-9001 facility. Calibrations are performed to NIST traceable standards.

Data output can be configured as fast as each minute, or with longer averaging intervals. Send data directly to the cloud for remote download and analysis with a CCS Modem accessory, and connect optional external meteorological sensors, as pictured here with the AIO 2 Sonic Weather Sensor.
