Miscellaneous

Electric sampling pump
This detector tube is suited for measuring p-dichlorobenzene 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.
