NIOSH physical description: Greenish-yellow gas with a pungent, irritating odor. [Note: Shipped as a liquefied compressed gas.]
Draeger short-term tubes are read on a Draeger accuro or X-act 5000 tube pump. Per the handbook (pp. 28–29), Draeger tubes and Draeger pumps are matched at the factory and form a single unit; other makers' pumps and tubes are not interchangeable with them. All Draeger tubes A–Z.

Draeger Chlorine tube questions
Which Draeger tubes measure Chlorine? CH24301 (0.2 to 3 ppm / 3 to 30 ppm), CH20701 (50 to 500 ppm).
What is the lowest range Draeger tube for Chlorine? CH24301, 0.2 to 3 ppm / 3 to 30 ppm, 10 /1 strokes.
What is the OSHA exposure limit for Chlorine? OSHA PEL C 1 ppm (3 mg/m³); NIOSH REL C 0.5 ppm (1.45 mg/m³) [15-minute]; IDLH 10 ppm (NIOSH Pocket Guide).
Which pump reads Draeger Chlorine tubes? The Draeger accuro hand pump or the X-act 5000 pump. MicroTubes, where listed, are read on the X-act 7000.
Do Draeger Chlorine tubes expire? Yes. The expiration date (month and year) is printed on the package; the handbook states a typical shelf life for the customer of up to two years, stored sealed at the temperature on the package strip (handbook section 2.13).
