This company's line of sensors work well with palm-size computers to make on-site environmental measurements easy. Available sensors include carbon Dioxide, carbon monoxide, air velocity, relative humidity, temperature and others. The system provides extensive application-specific software and provides a large, clear color display of measurements from the handheld computer screen. It also can provide storage for detailed descriptions of the measurements site or other information typed as a Microsoft Word document. Even handwritten notes and sketches made on the tactile screen can be saved. The system can be upgraded as needs warrant.
