dc.description.abstractThis study compares methods for measuring gaseous ammonia inside and outside of tunnel ventilated broiler houses. Instruments compared were colorimetric passive dosimeter tubes, colorimetric pull tubes, Drager Pac III electrochemical (EC) sensor, Environmental Sensors Inc. ZDL-800 EC sensor and Boreal tunable diode open path laser (OPL). Inside the house with tunnel fans running, all instruments compared well, although the dosimeter tubes indicated higher concentrations. When tunnel fans were shut off and ammonia concentrations increased, so did variation of all instruments, although the increase in variation with the OPL was minimal. During the outside comparison study, NH3 concentrations were too low and environmental conditions too harsh for the EC sensors and colorimetric tubes. The OPLs performed consistently outside, although the variation between them was higher during the outside comparison than the inside comparison.
