Pre-calibrated, direct-read detector tubes offer distinct lines of demarcation for easier viewing and require no interpretation, dual scales, or colour charts. With multiple detection limits for many chemicals the tubes can measure even trace levels of contaminants.

Additionally, Gastec’s higher maximum detection limits can provide a more accurate measurement of contamination. Offering some of the broadest operating temperature ranges available, the tubes can be used in virtually any environment—from 0°C to 40°C (32°F to 104°F).
