The model LDU-100 monitors PM10 and PM2.5.
As it updates the accumulated value of one minute every 10 seconds, it is optimized instrument for real-time measurement of the fine dust and ultra fine dust. Beside of one minute, the average value of 10 minutes, 30 minutes and 60minutes can be displayed. Optionally temperature-humidity sensor can be added and attach the batteries for portable use.
