MicroTubes for formaldehyde measurement, 5 to 150 ppb range

Dräger MicroTubes for formaldehyde (CH₂O) are short-term measurement tubes for the Dräger X-act 7000 analyser, covering 5 to 150 ppb. Formaldehyde is carcinogenic and irritating at concentrations well below one ppm.

  • Measuring range 5 to 150 ppb – matched to the concentrations that matter when you assess formaldehyde exposure or trace a leak.
  • Read out automatically by the X-act 7000 – the analyser evaluates the tube and shows the concentration directly, so there is no colour scale to judge by eye and no operator interpretation to defend afterwards.
  • Ready to use straight from the box – no calibration, no warm-up time and no sensor to replace; each tube carries its own batch data for the instrument to read.
  • A documented spot measurement in minutes – ideal where a permanently installed monitor would be disproportionate but a defensible reading is still needed.
