Drager Brand portable gas detector tube pump Model Accuro

Description

Fast measurement with one hand: The Drager-Tube pump accuro allows you to use the established Drager–Tubes to take measurements under extreme conditions.

The easy-to-use Drager–Tubes have already been calibrated and form a perfect unit with the Drager–Tube pump.

Benefits

Mobile spot measurement

This manual pump is used for spot measurements such as the detection of concentration peaks, confined space entry, worst-case scenarios etc.

Functional bellows pump

The Drager-Tube pump accuro draws in 100 ml per stroke. When measuring, the pump body (bellows) is pressed together completely.

The exhaust valve is closed during the opening phase of the bellows so that the gas sample flows through the connected Drager–Tube into the pump.

After the complete opening of the pump body into its original position the suction process is finished.

The end of stroke is visible by a pressurecontrolled end of stroke indication, located in the pump head.

Sampling

During the sampling process the substances to be evaluated are firstly accumulated on a suitable carrier material, e.g.

activated charcoal, silica gel and so on. The air to be evaluated is thereby drawn over the respective material – with a predefined flow rate and duration.

Afterwards, the substances that have accumulated on the carrier material through adsorption or chemisorption are examined

qualitatively and quantitatively in the laboratory using instrumental analysis such as gas chromatography.

One-handed operation

Frequently, measurements need to take place under extreme conditions, e.g. on ladders, in shafts or when wearing heavy breathing protection.

The Drager-Tube pump accuro can easily be operated with one hand and enables a reliable measurement also in difficult-to-access places.
