Atlantium OPB000100 — UV intensity sensor, measuring range 10 W/m². Atlantium Hydro-Optic systems monitor every lamp with its own UV intensity sensor (UVIS) and measure water UV transmittance (UVTS) continuously; the optical path and the temperature sensing must be intact for the dose control and the validated alarm set-points to remain valid. Spare part for Atlantium Technologies Hydro-Optic (HOD) UV water disinfection systems, which use medium-pressure lamps, a quartz treatment chamber working by total internal reflection, one UV intensity sensor per lamp and continuous UV-transmittance monitoring; installed in aquaculture, dairy and beverage process water, municipal drinking water, power-plant and industrial water treatment.
