Abstract

Research has been conducted to evaluate the results of automatic calibration the instrument CO Analyzer HORIBA APMA 360 at GAW Bukit Kototabang Station in period 2012-2015. Automatic Calibration is done by automatic zero and automatic span check check. Automatic zero check is done by entering the dry air free of carbon monoxide (CO) into the instrument. Automatic Span check is done by mixing the standard gas carbon monoxide (CO) concentrations of 44.86 ± 0:45 ppm with dry air free of carbon monoxide (CO) using a dilution unit into the instrument. Results of automatic zero check indicates there has been a deviation value of the concentration of CO from 2013 to 2015, while the automatic span check results show that most of the CO concentration values are far below the theoretical value (443 ppb)
