The Drager Hydrochloric Acid 20/a-D tube is a diffusion tube designed for long-term gas measurements. It has a measuring range of 20 to 200 ppm·h and works for up to 8 hours. This makes it suitable for monitoring Hydrochloric Acid, a colourless and corrosive gas, in various environments.

This tube is both reliable and cost-effective. Its 2-year shelf life ensures long-term usability, reducing the need for frequent replacements. The tube directly shows gas concentration levels, making it easy to monitor exposure. Additionally, it calculates the average concentration over the sampling period, which is displayed on the tube itself. This feature helps users understand time-weighted averages for better safety decisions.

One key benefit is its simplicity. The tube does not require a Drager Gas Detection Pump, making it a standalone solution for monitoring. It is also a practical choice for personal use, offering an affordable option for gas detection.

In summary, the Drager Hydrochloric Acid 20/a-D tube is an efficient, easy-to-use tool for monitoring Hydrochloric Acid. Its design focuses on clarity, convenience, and cost-effectiveness, making it ideal for both professional and personal safety applications.
