NUCLEAR Flame Photometer


Online, four channel Lithium detection

The measurement of lithium at low concentrations within nuclear power stations has been identified as an application perfectly addressed by a new specialty flame photometer – The BWB Nuclear.

Designed specifically for a customers' requirements, this unique flame photometer has 4 active channels for Lithium detection.

Each channel is independently calibrated within the range of interest and this results in an increase of accuracy in keeping with industry demand.

Our simultaneous detection and display from each detection channel satisfies the requirement specifically and the tie of one of the channels to 2 wire 4-20mA output via supervisory control and data acquisition (SCADA™) links, completes the unit for online use.
