ES-405 Simultaneous Particulate Profiler

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.

*TSP Measurements are indicative.
