    For the purpose of calculating sampling point spacing, the equivalent maximum area coverage for the VFT-15 is 1,500 m² (16,150 ft²) with 15 sampling tubes. The basic system includes RS232, RS485 and TCP/IP interfaces for connecting to the Xtralis VSC and Xtralis VSM4 software. When connected by TCP/IP, Xtralis VSM4 enables the configuration and monitoring of a large number of systems by a single PC, which can be accessed from anywhere via any standard internet connection.
