Key Features
- Hard-to-reach places can be accessed and measured using various compatible accessories
- Excellent for on-the-spot measurements
- 10 seconds to 15 minutes is the time frame for readings and is totally dependent on the tube type
- Suitable applications include pre-entry checks, confined space entry, variations in concentration levels and also contamination of breathing areas are amongst a number of potential of applications
Specification
| Application Range | |
