Dosimeter tubes
TWA measuring system (time-weighted average) – also known as dosimeter tube or passive tubes gas detection – measures the time-weighted average concentrations of a gas in ambient air.
- The dosimeter tube is inserted in its holder and wore close to the breathing zone (e.g. a shirt collar) to get an accurate measure of inhaled concentrations. This allows the monitoring of hazardous exposure during a working day.
- Thanks to this system, wokers can easily get daily exposure concentrations and evaluate working areas. These simple and direct measures require no specific analyzis instruments or complex operation procedures.
