The aim of this study is to evaluate ``online'' measurement methods of particle mass concentration of smokes in fire conditions. Three methods were used to measure simultaneously the particle mass concentration of smokes generated in a small compartment. The first method used a microbalance device (TEOM), the second one measured the optical extinction by particles (opacimeter), and the last one was based on the measurement of the current carried by charged particles (PPS). Three tests in the same conditions have been done in order to study the reproducibility of the measured values, which appears to be good. Differences have been observed between the results provided by the three methods caused by the calibration coefficients needed by each device to convert the measured parameter into mass concentration.
