Description

Convenient, long-term TWA monitoring—direct reading, with no lab analysis required

Tubes sample ambient air by gaseous diffusion with no pumps or moving parts. To use, break off the tube end with the special holder, put the tube in the holder, and clip it to your pocket or lapel.

  • Obtain time-weighted average (TWA) measurements of exposure to toxic gases for periods of up to 8 hours
  • Reagent changes color as it reacts with the airborne contaminant
  • Final results are calculated by dividing the tube reading by the number of hours it was used
  • Designed and manufactured using ISO 90001:2000-certified processes

Order Info

Use with accessory clip-on holder (Cat. No. 17-986-4; available separately below). Ten tubes per pack.

† Higher concentration measurements possible with reduced sampling time.
