ChemKey TLD
The ChemKey TLD is a toxic gas monitor that uses an optical scanning system to detect the presence of gas by a color change on a chemically-impregnated paper tape. Honeywell Analytics developed the ChemKey TLD Toxic Gas Monitor to provide emergency response and fixed area gas detection. The ChemKey TLK is capable of monitoring over 50 different gases, although not simultaneously.
