Wireless Indoor Air Quality Monitor
PPM Technology’s newest IAQ monitoring system, the Wireless IAQ Profile PPMonitor, enables simple, effective and flexible management of the indoor air environment.
The PPMonitor can continuously detect, measure and record a number of parameters, including temperature, humidity, formaldehyde, nitrogen dioxide, carbon monoxide, carbon dioxide, sulphur dioxide, ozone, ammonia and TVOC’s. Real-time functions enable immediate warnings of the presence of harmful gases in the air, thus protecting employees and the public. Hence buildings can be immediately evacuated giving minimal exposure to the building occupants.
The system has been designed to be easily set-up and operated. A manager PC simply connects to the wireless network using a Telegesis ZigBee USB module, allowing for the transmitting and receiving of information to and from a particular wireless unit.
The wireless units communicate via the ZigBee wireless mesh network which can be extended easily by adding repeater nodes or additional PPMonitor or Mini PPMonitor units. Each unit can be configured with unique sensor specifications if required, allowing complete monitoring of the indoor air environment in any building layout.
One wireless unit is connected to the Building Management System; BMS Software allows the entire wireless system to be managed from a single PC, the PC can preset a number of different exposure levels to trigger when limits are exceeded; these could be visible or audible alarms or used to control 3rd party systems such as ventilation systems.
The PPMonitor software enables the data to be viewed graphically and to produce reports and statistical data. Analysis of the recorded data over time allows for more efficient management of resources and energy.

Annual Salary Survey
In a year when manufacturing continued to lead the economic rebound, it makes sense that plant manager bonuses rebounded. Plant Engineering’s annual Salary Survey shows both wages and bonuses rose in 2012 after a retreat the year before.
Average salary across all job titles for plant floor management rose 3.5% to $95,446, and bonus compensation jumped to $15,162, a 4.2% increase from the 2010 level and double the 2011 total, which showed a sharp drop in bonus.
