Formaldehyde measurement CHOH 1 ppb

Formaldehyde measurement OFCEAS Durag

With this Durag OFCEAS for formaldehyde measurement we have a very long light path. This gives us a detection limit of no less than 1 ppb. One or more workspaces may need to be continuously measured for formaldehyde for personnel safety. It is clearly laid down in the law for how long at which dose of formaldehyde workers can be present in a room, and for how long. These formaldehyde concentration values ​​are very low, so a measurement system must be able to measure low value and be reliable. There are also versions for industrial applications as well as ATEX versions. Multiple measuring components can be added to measure simultaneously.

The main points of this formaldehyde analyser are:

  • continuous measurement
  • Ability to measure multiple components simultaneously
  • Low detection limit 1 ppb
  • no optically moving parts
  • The system can monitor formaldehyde at up to 16 different measuring points
  • No water condensation at measuring point due to low pressure
  • Self-calibrating system
  • Very fast measurement
