Dosimeter Tubes – TWA
Overview
Dosimeter (Dosi) tubes provide a user-friendly and economical way to monitor long-term exposure to airborne contaminants. Designed for either personal or area monitoring, these tubes require only passive exposure and visual reading—no additional equipment, calibration, or analysis required. Each tube includes a colorimetric scale for direct, on-the-spot concentration readings.

| Ready to Use | Pre-calibrated, direct-read design eliminates extra equipment and training needs. |
| Cost-Effective & Versatile | No need for repeated site visits or complex setups; great for various time periods (from minutes to 48 hours). |
| Accurate & Reliable | Each tube is labeled with production-specific calibration for traceability and precision. |
| Flexible Monitoring Modes | Use them as wearable personal monitors or install within work areas for area-level TWA readings. |
| Practical Applications | For example, in winemaking environments where SO₂ is used, these tubes verify safe dosages to both the product and workers. |

How to Use Dosimeter Tubes – TWA
Activate Tube
01- Snap off the scored end of the dosimeter tube and place it into the tube holder.
Deploy for Monitoring
02- Clip the tube holder to the worker’s breathing zone or area of interest. The tube samples passively over time.
Read & Calculate
03- Read where the color change stops on the tube scale (ppm·hours). Divide by the exposure time (hours) to convert to ppm TWA concentration.
