Spectroradiometer UVpad E: Precise, spectral UV measurements

The compact spectroradiometer SR900 is a high-resolution measurement system for quick and precise measurements in the UV range, the visible spectral range and the IR. The spectroradiometer consists of an array spectrometer without any moving parts and a silicon detector with 2048 pixels. The spectral resolution is 0.4 nm. The SR900 is combined with a SMA-905 quartz light light guide and our radiometric sensor heads for measuring the irradiance and illuminance.Traceable to the PTB, the SR900 is factory-calibrated. A DAkkS test in our accredited laboratory is optionally available. The SR900 thus enables exact spectroradiometric measurements for the assessment of irradiances and illuminances, biological effectiveness and color measurements. Due to the nearly scatter-free construction, a high sensitivity in the UV range is reached. Control and data evaluation is carried out by the spectral software SRpro. With trigger input and output, the SR900 is also suitable for automated measurements.

The industrial spectroradiometer iSR900 is an autonomous and high-resolution measuring system for fast and precise measurements in the UV, visible spectral range and IR. The spectroradiometer consists of an array spectrometer without moving parts and a silicon detector with 2048 pixels. The spectral resolution is 0.44 nm. The iSR900 is combined with an SMA-905 quartz light guide and our radiometric measuring heads for irradiance and illuminance measurement. The iSR900 is factory calibrated to PTB. A DAkkS test in our accredited laboratory is optionally available. The iSR900 thus allows accurate spectroradiometric measurements for the evaluation of irradiance and illuminance. The low-scatter design achieves high sensitivity in the UV range. Control and data evaluation take place in the iSR900 so that only a USB or RS485 / RS232 interface is required for the evaluation. With trigger input and output the iSR900 is ideal for automated measurements.

The UVpad is the world‘s thinnest spectral measuring and autonomous UV radiometer. It combines scientific measurement technology with a compact and user-friendly instrument. With its innovative measuring principle, it doesn't use optical filters. UV light is spectrally detected and analyzed in the UVpad. Thus, measurements are traceable to national standards. Since it works without a filter, it is particularly suitable for the measurement and comparison of different lamps. All measurement data are displayed on the device immediately; 50 measurements are stored in the UVpad and can be read via USB. The supplied PC software evaluates the irradiance intensity profiles measured separately for UVA, UVB, UVC, and VIS. Spectrum and measurement data can be exported and saved. Optionally, UV systems can be optimized due to saved operating functions such as, for example, the absorption spectra of photo initiators. Thus, the operation costs can be reduced and the product quality can be ensured.

The PLC UV sensors and VIS sensors serve as precision sensors for the measurement of UV irradiances and illuminances in systems with programmable logic controllers (PLCs). Spectral range, measuring range, operating voltage, and output signal can be selected to match the measurement task and the PLC. The integrated electronics generate a signal voltage that is transmitted with the low interference cable to the PLC. The built-in diffusers provide the required cosine correction. The sensors are calibrated with traceability to the PTB (Physikalisch Technische Bundesanstalt, the German national test authority); after being calibrated, they are shipped with a factory calibration certificate. Excellent long-term stability is achieved through the use of appropriate materials. Of course, a repair and spare parts service is available for many years. Our product range includes eight spectral ranges and three measuring ranges for the sensors.
