  • Page 11: Introduction

    2 Introduction 2.1 Unpacking When you unpack the E-Sampler and accessories, inspect the carton for obvious damage. If the carton is damaged notify the carrier. Unpack everything and make a visual inspection. The E-Sampler is shipped with the following accessories:...

  • Page 12: E-Sampler Overview

    An internal visible laser diode is collimated and directed through sample air. This sample air is drawn into the E-Sampler by an internal rotary vane pump. Flow rate is controlled based on actual conditions for accurate cut-points through the sharp-cut cyclone.

  • Page 13: Getting Started

    K factor is computed. The E-Sampler does not need to be operated with a 47 mm filter. All that is required is the 47 mm cassette to seal the flow system.

  • Page 14: Inlet Heater

    4. The tab on the bottom of the E-Sampler can either be bolted to the pipe or clamped using a similar hose clamp.

  • Page 15: Power

    Figure 4 Inlet Heater installation 1. Insert the aluminum inlet tube into the E-Sampler top. Connect the Heater power connector. 2. Remove the plastic nut, washer and rubber gland fitting from the plastic housing 3. Slide the plastic housing over the aluminum inlet tube and align the holes in the housing with the mating holes on the top of the E-Sampler.

    590807. For a complete list of spare parts and consumables see section 3.3.6. For external battery connection connect the external battery cable to the battery and plug the watertight connector into the bottom of the E-Sampler enclosure. See Figure 6.

  • Page 17: Using The Menu System

    2.3.4 Using the Menu System Applying power to the E-Sampler brings up the Intro screen for 5 seconds, which details the firmware version, used in the E-Sampler. After the Intro screen the E- Sampler defaults to the OPERATE screen. The real-time concentration, current time, flow rate and sampling condition are displayed.

  • Page 18: Operation Of The E-Sampler

    Figure 7 Clean air condition for the E-Sampler Nephelometer. This clean air condition without scattered light is the auto-zero condition. During an Auto-zero the E-Sampler filters the air through a 0.2-micron pore size 99.99% efficient filter element before it enters the sensor. The E-Sampler will automatically zero itself on a programmed basis.

  • Page 19: Figure 8 Light Scatter Due To Airborne Particulate

    Particulate weight per unit volume (mg/m3) is the standard measurement for the E-Sampler. Met One has found that the relative humidity (RH) of the air has an influence upon the measurement of particulate weight by nephelometers. A recent study in Atmospheric Environment showed that RH could drastically affect the concentration measurement.

  • Page 20: Filter Collection System

    Figure 9 Measured concentration increases with increasing RH. The E-Sampler prevents this through a unique heated inlet that uses an internal RH sensor. The RH of the incoming air is measured and at a customer set point the inlet heater is activated to keep the RH from changing the true concentration.

    K-factor. See section 3.2.3 for details on this procedure. 3.1.3 Flow System One of the automated tests the E-Sampler does to assure quality data is the Auto- Zero. This feature is possible because of a unique Met One flow system. The DC pump is able to reverse the flow direction when the voltage polarity is reversed.

  • Page 22: Data System

    MicroMet Plus or Air Plus software. Standard to the E-Sampler is a powerful 10-channel data logger. A complete met system can be connected to the E-Sampler and used for data validation or air pollution studies. Every E-Sampler comes standard with ambient temperature and pressure.

Each E-Sampler is supplied with TUS software. This software automatically finds connection speeds, and hardware used to download data (i.e.

  • Page 24: Using The E-Sampler

    To Start a continuous sample connect the E-Sampler to a power source. See section 2.3.3 for a complete list of power options. If the E-Sampler does not start press the TURN ON soft key shown in Figure 11.

  • Page 25: Timed Operation

    This screen has two date inputs – Start time and sample duration. The Start time is the Day and time that the E-Sampler will begin to sample. The duration is the length of time the E-Sampler will continue to sample. This feature will allow the E-Sampler to start a sampler period in the future to conserve battery life or to meet collocated criteria.
  • Page 26 /hr = 0.0042 mg/hr 0.500 mg / 0.0042 mg/hr = 119 hours or 5 days. 5. Program the E-Sampler to Operate in Timed Mode for the duration calculated from step 4. 6. After the sample period has ended from step 5 remove the gravimetric filter and reweigh.

  • Page 27: Maintaining The E-Sampler

    3.3 Maintaining the E-Sampler 3.3.1 Flow Calibration Flow rate is important in the E-Sampler for two reasons. The primary reason is for the cut point in the sharp cut cyclone. The momentum of the particles determines the cut point in a cyclone. Momentum is a product of the velocity multiplied by the mass.

    1. Select the lowest SETPPOINT. 2. Connect the reference flow meter to the inlet of the E-Sampler. The reference flow meter should have accuracy of 1%. 3. Wait for the pump to stabilize – approximately 2 minutes.

  • Page 30: Pump Maintenance

    The part number to order a new pump is 680847. 1. Remove the inlet see section 2.3.2. 2. Disassemble the E-Sampler electronics by removing the 4 Phillip head screws. 3. Carefully remove the electronics module. Set the module down on a clean static-free work mat.

  • Page 31: Inlet Cleaning

    Cleaning requires compressed air, isopropyl alcohol, and a lint free cloth. Remove the inlet(s) from the E-SAMPLER and disassemble as shown in Figure 17. Clean the TSP inlet head by loosening the 3 screws and separating the head into two parts.
