Detector tube (Gastec) Formaldehyde 91L 1 box

The concentration of various gases in the air can be easily measured using a direct reading method. Measurements can be performed using just one detector (pump) by simply changing the detector tube. Since it is a direct reading type, it is accurate and there are no individual differences. Concentration measurement is completed in 30 to 240 seconds for one stroke (100 ml).
