The Nitrolux is Pranalytica's flagship ammonia sensor. The Nitrolux detects ammonia at less than 100 ppt levels. It uses a patented laser tuning technology for zero interference from common laboratory solvents. Pranalytica's sensors provide simultaneous multistream capability for up to 8 gas streams. They run on an embeded Linux system with solid state memory and a powerful graphical user interface, and can be monitored and controlled over the Internet. Pranalytica's sensors can be deployed in remote locations where there is no easy access to wired networks, or land lines. They work on solar cells and come with an optional cellular modem that communicates to the Internet via a cellular network.
