Long-duration measurement detection tube fixed holder / Part number M176DT-LTM710G
Attach a passive long-term measurement detection tube to the worker's breathing zone, such as at the collar.
You can measure individual exposure levels, fix them in the workplace, and easily understand the concentration distribution in the environment or daily fluctuations.

Applications/Examples of results
■Passive Long-Term Measurement Detection Tube The passive long-term measurement detection tube measures the average gas concentration over an extended period (time-weighted average concentration) by utilizing the natural diffusion of gas. By inserting a diffuser (diffusion inducer) parallel to the detection agent inside a glass tube with a constant inner diameter, it facilitates and stabilizes gas diffusion, creating a highly sensitive and sharp discoloration layer. The passive long-term measurement detection tube can be installed at the collar area of the worker's breathing zone using the M176DT-LTM710G to measure personal exposure levels, or it can be fixed in the workplace to easily determine the distribution of environmental concentration or daily fluctuations. ● Compact and lightweight, it does not interfere with work and can be placed anywhere for measurement. ● Simple direct measurement, no analytical operation required. ● No sampling device needed.
