Tiger-i 2000 CH2O

Formaldehyde (CH2O) is a known human carcinogen and as such, the accurate and effective measurement of this pollutant in our environment is critical. Indoors, formaldehyde is present in many man-made materials such as pressed wood products, carpets, and adhesives. We are also exposed to formaldehyde when using modes of transport powered by the combustion of fossil fuels.

Tiger Optics delivers a powerful analytical tool for the measurement of trace CH2O for diverse applications. Based on powerful Cavity Ring-Down Spectroscopy (CRDS), with a proprietary laser-locked cell, the Tiger-i 2000 is free of drift, guaranteeing consistent and reliable trace CH2O detection in ambient air. Highly specific to the target molecule, CRDS also prevents cross-interferences from distorting your measurement. Plus, there is no need to perform costly and time-consuming zero and span calibrations, saving both time and money with continuous, on-line service. The Tiger-i 2000 CH2O gives you unsurpassed speed of response and ease of use.

In sum, the Tiger-i 2000 CH2O analyzer serves a range of applications where trace gas measurement is extremely critical, such as indoor air quality monitoring, assessing outgassing from building materials, and optimization of vehicle powertrains. The Tiger-i 2000 CH2O builds on Tiger Optics longstanding leadership for trace monitoring of critical compounds.

Designed for formaldehyde analysis in laboratory, process, and indoor air quality applictions, as well as the detection of Airbourne Molecular Contaminants (AMCs), the Tiger-i 2000 CH2O offers:

  • Accuracy traceable to the world’s major reference labs
  • Freedom from the need for span calibrations
  • No periodic sensor replacement/maintenance
  • 10 ppb detection limit in ambient air
  • Wide dynamic range and no drift
