The UV-Datalogger USB is a small, self-contained, high quality UV monitoring instrument for long-term data
recording. 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 a 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)
The UV-Datalogger USB is available in various versions and five different measuring ranges:
