FOREWORD Thank you for purchasing the Model AP-20S sampling pump. The Model AP-20S pump is designed specifically for use with Kitagawa detector tubes. This system with the available Sensidyne/Kitagawa detector tubes can detect the presence of more than 300 airborne gases and vapors. -
Page 4: Notes
Any service or repair must be followed by a leak check prior to field use. • Note that the AP-20S pump is a vacuum pump only, and it cannot be used for specialized detector tubes that require sample entry by pressure (Oxygen, Hydrogen, Propane, etc.) -

Page 7: Performing The Leak Test
If the pump fails the leak test, the following are possible causes: A) A loose inlet connector holder. B) Cracks and deterioration of the rubber tube connector. C) Deterioration of the grease. To correct a leaking pump, consult the MAINTENANCE section. © 2003 Sensidyne, Inc. -
Page 8: Maintenance
MAINTENANCE • Lubricating The Pump Pull the handle part way and turn the bottom case counterclockwise to remove it. Pull the piston out from the cylinder. Wipe off the old grease and dirt from the piston and inside the cylinder using a clean paper towel. Apply a thin coat of grease to the rubber gasket of the piston. -
Page 9: Operating Procedure
Pull the tube toward you at an angle to break the tip. Repeat this for the tip at the other end of the tube.

Page 12: Temperature Correction
TEMPERATURE CORRECTION The temperature of concern is that of the detector tube (usually the temperature of the sample gas). • USING A CORRECTION TABLE ° [Example] When the tube reading is 550 ppm at 25 C the true concentration is found by interpolating between the concentra- tions listed for 20°... -

(e.g., A glass syringe of 100cc or 200cc or a Tedlar bag of 1 to 2 liters is a suitable con- tainer). When flue gas or other high temperature gas is sampled, use the Hot Air Probe. © 2003 Sensidyne, Inc. -
Page 14: High Concentration Gas Measurement
Measurement under Special conditions • High Concentration Gas Measurement High concentration gas ex- ceeding the measuring range of the detector tube may be sampled as follows. Collect a volume of sample gas into a glass syringe and dilute with fresh air. (See photograph). The tube reading is then mul- tiplied by the ratio of dilution to determine the actual con-... -

One-Hand Adapter The one-hand adapter for the Sensidyne Model AP-20S Pump is ideal for one hand sampling from a ladder or into hard-to-reach places. With the adapter installed and a tube inserted, the pump handle can be drawn and locked without actually taking a sample. - Page 16 Proudly Distributed By: “The Standard for Professionals” ™ 16333 Bay Vista Drive • Clearwater, Florida 33760 USA 800-451-9444 • 727-530-3602 • Fax: 727-539-0550 www.sensidyne.com • info@sensidyne.com...
