Apparatus

1.An aerosol photometer ATI model 2D, 2E, 2G or equivalent. Air Techniques Hamilton Associates inc. 11403 Cron Ridge Dr. Owings Mills, MD 21117

2.One aerosol generator of the Laskin nozzle(s) type. An aerosol of mineral oil or suitable liquid shall be created by flowing air through it. The compressed air supplied to the generator should be adjusted to a pressure of 10± 1 psig. during operation. Air Techniques Inc. Model TDA-4A or equal. One nozzle at 10 psig is (67.5 cfm x 100ug/l)/(Vol. of air), For the 2' at 90 fpm or 130 cfm, one nozzle @10 psig is 13,500/130 cfm = 52 ug/l. For the 3' at 90 fpm or 200 cfm, one nozzle @ 10 psig is 34 ug/l. For the 4' at 90 fpm or 265 cfm, one nozzle at 10 psig is 26 ug/l.

3.Mineral oil (Catalog #1491400).

4.Sampling Nozzle, Rectangular 1/2" x 3-1/4", Air Techniques, Inc.

Procedure

For the ATI 2G Photometer

1.Turn on the photometer and allow it to operate for a minimum of 5 minutes. Leave the valve in the “CLEAR” setting.

2.Press the “ENTER” keypad. Press the “REF” keypad.

3.The display will display “P1” for approximately 1 second, and then display a numerical value.

4.Using the “^” or “ν” keypads, respectively, increase or decrease the numerical value until it equals 52 (2'), 34 (3'). 26 (4') for the enclosure at 90 fpm inflow velocity.

5.Press the “ENTER” Keypad. The photometer will scan for 15 seconds, and then the “0” keypad will flash. Press the “Enter” keypad. The unit will scan for 5 seconds, the display will read “0000,” and the unit will sound a confirming tone.

6.Set the valve to “DOWNSTREAM.” Place the palm of your hand over the sampling port of the pistol. There should be a strong vacuum at this port. If the vacuum is weak, contact Air Techniques Hamilton Associates.

7.Turn the enclosure on and let it operate for a minimum of 5 minutes.
