The Carl Stuart Group was founded in 1984 by Stuart and Gillian Smith. From a small beginning our business has grown to encompass many services and products, covering different market sectors and geographical regions. The focus of our business, however, remains the same. We are a customer orientated company and strive to meet and exceed your expectations in everything we do.

As our portfolio grew we decided to present and promote our product and technical service offerings under distinct brands.  The Laboratory instrumentation, consumables and technical & integration services are promoted under Lab Unlimited.

LISA UV254 Sensor: Cutting edge UV-LED technology from TriOS

LISA UV254 Sensor: Cutting edge UV-LED technology from TriOS

LISA - The state of the art SAC254 sensor by TriOS

The LISA UV sensor from TriOS combines long-lasting, energy-efficient UV-LED technology with a robust, durable design. By using unique nanocoated windows along with compressed air flushing, they allow for long operating times without cleaning - as do all TriOS sensors.

Integration of the sensor into existing process control systems or external data loggers is made quick and easy due to the TriOS G2 interface.

This makes the LISA UV sensors easily configurable through any standard web browser on a PC, tablet or smartphone. These sensors are also available with digital or analog output, in addition to the integrated network interface.

Very versatile, the optical path length can be easily adapted to your application, at any time, by using different lens sockets. An automatic turbidity compensation is carried out by a second measuring channel.

Through application-specific correlation LISA UV can be configured for direct output of BODeq, CODeq, TOCeq. A direct output of UVT254 is also possible.
