Drager Detection Tubes - Carbon Monoxide 2/a (Pack of 10)
Drager’s short-term gas detection tubes are a reliable way of accessing measurements of many different gases. These particular tubes are for carbon monoxide (2/a) and have a measurement range of 2 to 300 ppm.
They have a shelf life of 2 years, come in a pack of 10 tubes and are also able to detect carbonyl sulphide.
The Accuro Gas Detection Pump from Draeger Safety is required to use short-term gas detection tubes. View more information on this product by clicking here.
- Reach difficult measurement areas with the tubes, pump and accessories
- Carry out measurements on the spot
- Measurement results may take between 10 seconds and 15 minutes depending on the type of tube uses
- Applications for use include variations in concentrations in the workplace, contamination of breathing zones, pre-entry checks and confined space entry
