The instrument is a 2-beam 256 pixel UV/VIS spectrometer, with a Xenon lamp as a light source.
On-board electronics control the entire measurement procedure. All of the controller electronics are
included in the 44 mm tubular anodised aluminium housing and include a data logger and a water
level meter. The communication is via RS232 or RS485 interface. The power supply can be by
means of AC 220 V/50 Hz or DC 12-24 V, respectively. The low power consumption eases field
application by means of battery or solar power supply. The probe has a data logger on board,
capable to store e.g. complete absorption spectra of 1 month at a measuring interval of 30 minutes.
