The Omega HHAQ-107 meter is ideal for making general measurements of mixed gas volatile organic compound (VOC) levels as part of an IAQ maintenance program. Since people spend most of their time inside homes, schools, and commercial buildings, measuring the health and comfort in the air is important. The HHAQ-107 can detect ammonia, toluene, ethanol, hydrogen sulfide (H2S), and cigarette smoke. Features include 32,000 data logging points, free data logging software, and an adjustable high VOC concentration audible alarm.
