For 25 years, Dr. Groebel UV-Elektronik manufactures precise measuring devices for the UV and the visible spectral range. The product portfolio includes precise hand measuring tools, robust process measuring equipment and powerful UV/VIS spectrometers. Exact quantitative radiometric and spectroscopic measurements are guaranteed by calibration of measuring devices with respect to a PTB (Physikalisch-Technische Bundesanstalt) reference. Product group Description Major applications UV/VIS Spectrometer Fast multichannel UV/VIS spectrometer with high dynamics and calibration to PTB reference Spectroradiometry, Transmission, reflection, diffuse reflection, colour measurement, multicomponent gas analysis Photometers Devices for transmission measurements of gases, liquids and solids Water quality, purity of chemicals, testing transparent plates, fume gas analysis Radiometers Precise handheld radiometers and UV monitors traceable to PTB reference Irradiance of lamps, irradiation systems, dosimetry, radiation safety UV-VIS Sensors UV and visible sensors for measurements with radiometers and PLC system controllers Luminescence- Measurement Sensitive device for the detection of luminescent / fluorescent substances Process monitoring, leak detection, coating control, trace detection Integrating Spheres Generation of diffuse radiation or integration over irradiation angle by diffuse reflection within a sphere Uniform light source, measurement of diffuse reflection, transmission, irradiation power, detector calibration
