PPM Technology’s newest IAQ monitoring system, the Wireless IAQ Profile PPMonitor enables simple, effective and flexible management of the indoor air environment, the company said. The PPMonitor can continuously detect, measure and record a number of parameters, including temperature, humidity, formaldehyde, nitrogen dioxide, carbon monoxide, carbon dioxide, ozone and ammonia, the company said. Real-time functions enable immediate warnings of the presence of harmful gases in the air thus protecting employees and the public. The system is designed for easy set-up and operation, the company said. A manager PC simply connects to the wireless network using a Telegesis ZigBee USB module, allowing the transmission of information to and from a particular wireless unit. The wireless units communicate via the Zigbee wireless mesh network, and the network can be extended by adding repeater nodes or additional PPMonitor or Mini PPMonitor units, the company said. The PPMonitor software enables the data to be viewed graphically. It can also produce reports and statistical data.
