  • Page 5: Introduction

    This document is organized with the most important information grouped together for easy reference by the user. All ES-412 owners and operators should read and understand the sections on installation, setup, and field calibrations. Other sections that provide in-depth information on subjects such as theory, diagnostics, accessories, and alternate settings provide valuable information which should be consulted as needed.

  • Page 6: About The Es-412

    Laser Light Scatter System Sample air is drawn into the ES-412 detector chamber and subjected to an intense laser beam located at right angles to the flow. Particles pass through the laser beam and scatter light that is collected by a photodiode detector.

  • Page 7: 412 Specifications

    Always power down the system whenever service or repair work is being performed inside the instrument enclosure. Only trained technicians should attempt to repair the ES-412. Routine maintenance does not require removing the instrument from its weatherproof enclosure. 1.5 ES-412 Specifications...

  • Page 8: 412 Setup And Startup

    2 ES-412 SETUP and STARTUP The ES-412 is designed for rapid deployment and easy setup by a single person in less than 15 minutes in most applications. This section describes the basic assembly, setup, and start-up of the instrument. 2.1 Standard and Optional Accessories When unpacking a new ES-412, verify that the contents are undamaged.

    2.5 Power-Up and Starting Operation As soon as power is applied to the ES-412, the unit will automatically begin to sample and report data to the Cloud at the proper interval (15 minutes in the USA standard, 5 minute optional, 60 minutes Global version, 15 minute rate optional).

  • Page 12: Downloading And Viewing Data

    3 DOWNLOADING and VIEWING DATA Currently, Met One offers two options for downloading and viewing the data from an ES-412 system; a web interface and a windows application. This section will cover both options. 3.1 Web Interface The first method for downloading and viewing the data is through the web portal. Each customer will be sent a private link to a custom dashboard in which users can view, chart, and download/export their data.

    3.2 Comet Software The ES-412 is compatible with the free copy of the Comet™ program. Comet is a simple, Windows- based, communications terminal program developed by Met One Instruments, Inc. Comet allows the user to connect to the cloud and download the data from each cloud service webpage.

  • Page 14: Comet Installation

    Download the Comet software onto a PC and run the Windows Installer Package. Follow the on- screen instructions until Comet is successfully installed, then run it from the Programs directory. Create a new station for the ES-412 and use it to retrieve the data from the monitor. 3.2.2 Setting up a Cloud Station The first time the Comet program is opened it prompts the user to create a new station for your Cloud site.
  • Page 15 Select the Met One Cloud Product Type and click next. Enter a Station ID, API key, and Serial Number for the ES-412. Note: Customers will receive an API on the provided configuration sheet; a digital copy can be obtained from the Met One Instruments Service department.

  • Page 16: Data Plans And Renewals

    When Comet downloads the data, a CSV file is created in the users My Documents folder. 4 DATA PLANS AND RENEWALS The ES-412 includes three years of cellular data and website hosting at no extra charge. The cloud service can be renewed by contacting the Met One Service department at service@metone.com 541-471-7111.

    Sample air is drawn into the ES-412 by an internal pump. Flow rate is controlled with a flow sensor to maintain constant 1 LPM flow on the inlet nozzle. Additional air is added around the sample flow to contain the particles.

  • Page 21: Sample Rh Control For Light Scatter Mass

    24-hour data. Calculate the K-Factor for each particulate size fraction as the reference concentration divided by the ES-412 light scatter concentration over the same time period. For example, if the reference total concentration was 51 μg/m and the ES-412 total concentration was 38 μg/m , then the K-Factor would be 51 divided by 38 or 1.342.

  • Page 22: Maintenance And Troubleshooting

    The ES-412 Particle Profiler should be calibrated on a 24-month basis. Basic Problem and Cause/Solution Table The following table contains information on some of the more common ES-412 problems which may be encountered, and some steps to identify and remedy the problems.
