Drager Model 31 Multi-Gas Detector Pump with 30 Assorted Tubes

The Dräger Model 31 V-100 multi-gas detector pump is a low-cost, one-handed bellows pump that is ideal for measurements in hard-to-reach areas. It takes short-term measurements with reasonably few strokes when used with Dräger short-term detector tubes.

Dräger tubes are glass vials filled with a chemical reagent that reacts to a specific chemical or family of chemicals. A calibrated 100mL sample of air is drawn through the tube with the Dräger bellows pump. If the targeted chemical(s) is present the reagent in the tube changes color and the length of the color change typically indicates the measured concentration.

These units are in good condition and each includes your choice of 30 Dräger short-term tubes (all appear un-used). The available tubes are as follows:

2 x Acrylonitrile (0.5 to 20ppm)

8 x Arsine (0.05 to 3ppm)

8 x Chlorine (0.3 to 5ppm)

5 x Dimethyl Sulphide (1 to 15ppm)

8 x Ethylene Oxide (25 to 500ppm)

22 x Formaldehyde (2 to 40ppm)

5 x Hydrochloric Acid (1 to 10ppm)

4 x Hydrocyanic Acid (2 to 30ppm)

7 x Iodine (0.1 to 5ppm)
