Are direct reading method acceptable for the reading of parameters for Particulates, CO2, CO and Ozone? The reference method used are complied to the Leed however. Does any calibration of the measurement device need and should the calibrated report presented for submission if direct reading method acceptable for air testing? So far the measuring device used are Aeroqual S5000 for ozone; TSI Dustrak 8533 Aerosol monitor (gravimetric samples) for particulate (PM10 & PM2.5) and TSI VeloCicalc for CO, CO2, RH and temperature monitoring.

 Thanks in advance.
