Chelsea provides a range of compact PAR, turbidity and bioluminescence sensors. The Chelsea GlowTracka is a robust and sensitive detector primarily used for the assessment of bioluminescent algae within the marine environment. The Chelsea PAR sensor provides an impressive range of sensitive Irradiance measurements down to depths of 1000 metres. It is ideally suited to monitoring marine photosynthesis, where the prime concern is to quantify the amount of PAR available. The UniLux Turbidity is a compact sensor for monitoring real-time turbidity in natural and process waters.
