CRDS Laser-Based Analyzer
ADVANCING ACCURATE, CONSISTENT & DRIFT-FREE CH2O MEASUREMENTS
Designed for formaldehyde analysis in laboratory, process, indoor and outdoor air quality applications
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. Our Tiger Optics’ T-I Max AIR CH2O analyzer delivers a powerful analytical tool for the measurement of trace CH2O for diverse applications. Based on powerful our Cavity Ring-Down Spectroscopy (CRDS), with a proprietary laser-locked cell, the T-I Max 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. Our T-I Max AIR CH2O gives you unsurpassed speed of response and ease of use. The T-I Max AIR CH2O analyzer serves a range of applications where trace gas measurement is extremely critical, such as indoor and outdoor air quality monitoring, assessing outgassing from building materials, and optimization of vehicle powertrains.
BENEFITS
- Accuracy traceable to the world’s major reference labs
