Inexpensive state-of-the-art UV254 absorption photometer. The integrated UV-LED technology ensures a long product lifetime.
Long-lasting and energy-efficient UV-LED technology and a robust design are the core features of LISA UV. LISA UV uses unique nanocoated windows and compressed air flushing to achieve long operating times without cleaning.
Various lens sockets can adapt the optical path length to the application at any time. An automatic turbidity compensation is carried out by a second measuring channel. Through application-specific correlation, LISA UV can be configured for direct output to BOD, COD and TOC. A direct output of UVT254 is also possible.
The TriOS G2 interface allows quick and easy sensor integration into existing process control systems or external data loggers. In addition to the integrated network interface, LISA UV is available with digital or analog output. The sensor can easily be configured through any web browser on a PC, tablet, or smartphone.
The sensor also able to configure to Stationary Online model together with user friendly interface from TriBox Mini or TriBox 3 which able to configure Self Cleaning Interval, alarm output setpoint, 4-20mA range Output or Wifi Connection to PC, Tablet or Smartphone.
The TriOS Sensor also able to perform Self Cleaning with Air Cleaning Option — Video Link
