It is designed to measure and record UV energy in mW/cm2 e.g. of low pressure HG lamps for the water purification. Various customer specific configurations are available and in conjunction with a high pressure, water proof sensor housing it is particularly suitable to monitor UV-energy of water disinfection installations. It is available with different UV-sensors in up to five different UV-bands (UV-A, UV-B, UV-C, UV-V –Diazo- or full UV).In the basic version the UV-Datalogger USB consists of the measuring head, which is fixed to the lamp housing, and the removable USB recording stick. The UV-Datalogger USB is also available with an optional flexible optical light guide and SMA socket to enable measuring in high temperature areas (up to 350 °C/ 660°F). The detachable USB stick can record up to 32.000 measuring results.

The sampling rate decreases reciprocally in relation to the recording period. At the highest sampling rate of 1 sec the maximum recording period is approx. 9 hrs, while at a sampling rate of 5 min the recording period reaches 3 months.The UV-Datasampler USB comes with a special evaluation software for downloading the data to a computer to show, edit and store a history of the monitoring results of the entire measuring period as graphic charts (mW/cm2).
