The UV-DATALOGGER USB is a small, self-contained, high quality UV monitoring instrument for long-term data recording.
+ Wireless data acquisition
+ Long-term data acquisition (up to 3 months)
+ High sampling rate (up to 1/s)
+ UV-intensity mW/cm2
+ Up to 5 different UV-bands available
+ USB connection
+ Graphic chart on PC
+ Evaluation software
+ Optical light guide for high temperature (optional)
+ High-pressure housing for water disinfection available
+ Simple installation

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/ 660F). 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:

UV-Datalogger USB, Type 1 UV-V (Diazo) 350 460 nm
UV-Datalogger USB, Type 2 UV-A 315 400 nm
