Met One ES405 Particulate Profiler
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.
This unit reports four key particulate concentrations in both indoor and outdoor environments. The rugged weatherproof enclosure allows it to be used in the toughest environments for reliable continuous outdoor operation. 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 unit can be wall mounted or installed on a vertical mast. 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 2 accessory. External meteorological sensors can be connected to the unit.
Features & Specifications
- EEars for mounting
- USB cable
- Weatherproof inlet
- Optional tripod and mounting bracket.
