An easy method for testing containers and other spaces for the presence of fumigation agents. A specially developed measuring strategy allows for the detection of fumigants even when the chemical is unknown. To prevent goods from being damaged by animals such as insects and other disease carriers, containers are flooded with toxic or suffocating gases. Fumigants are highly toxic and harmful to the health in many ways and the concentration of the fumigants must be measured. Thereby, it is important to check the Oxygen concentration in the container or other spaces. In only a few minutes, the concentration of the fumigants within the container can be determined, and depending on the concentration measured, the decision can be made whether the container or space can be entered or ventilated. All that is needed are the corresponding tubes, the Drager accuroR hand pump, and the Drager bar probe. By comparing the color change within the detector tube to the printed scale, an estimation of the concentration can be made. If the fumigant is known, the corresponding Drager-Tube is chosen and the measurement carried out as instructed. Fumigation test set is composed of the following equipments : *Fumigation case #83 17 147 *Gas detector pump #64 00 000 *Bar probe 400 for the measurement of fumigants in the container #83 17 188 *Extension hose for Draeger Accuro, I mtr #64 00 561*Adapter Draeger Simultest, consisting of cutting holder and adapter #64 00 090 *Spare parts set for Draeger Accuro #64 00 220.
