Draeger Model 31 V-100 Multi-Gas Detector Bellows Pump with Case and Short-Term Tubes

The Draeger Model 31 V-100 Multi-Gas Detector Pump is a compact, lightweight, and cost-effective bellows pump designed for portable gas sampling in confined or hard-to-reach environments. This pump operates with Dräger short-term detector tubes, which are glass vials filled with selective chemical reagents that undergo a colorimetric reaction upon exposure to specific gases or vapors. By drawing a calibrated 100 mL air sample through these tubes, the device enables quantitative detection of various hazardous gases by measuring the color change length, correlating directly with concentration levels.

Key technical features include:

This gas detector pump is widely adopted in industrial hygiene and environmental health research to monitor toxic and combustible gases, making it critical for ensuring workplace safety and compliance with occupational exposure limits. It is particularly effective in biopharmaceutical production pipelines where controlling gas exposure can impact process integrity and personnel safety.

Please specify desired short-term tube types and quantities to customize detection capability for your specific research or monitoring needs. Refer to the linked manual for detailed operational parameters and tube equivalencies.
