| Calibration gas generation | Permeation tube method |
| Electric sampling pump This detector tube is suited for measuring toluene in indoor environments. The GSP-200 / GSP-300FT-2 series automatic gas samplers （or comparable sampling devices/pumps） should always be used for optimal performance. A deviation of +/-10% in the sampling flowrate （i.e. amount of air flowing through the tube at a given moment） or the sampling amount （total sampled amount of target substance） causes an average margin of error of approx. +/-10% （maximum +/-20%） in the indicated value. |
