    Atlas XenoCal sensors are Atlas’ premium calibration sensors with ISO 17025 certificates for both irradiance and BST calibration sensors. All XenoCal sensors are easy-to-use with software XenoSoft analytical software for the quick visualization and analysis of the measured values.

    Apart from primary use as Atlas instrument calibration tools, XenoCal sensors can also be used as individual data loggers to record irradiance or BST temperature in a specific environment.

    Atlas provides a special model XenoCal Solar for the PV industry. XenoCal Solar can take precise measurements for UV pre-conditioning of PV modules as specified in IEC standards for crystalline (IEC 61215) and thin-film (IEC 61646). The sensor operates at temperatures up to 70 °C and also is water-tight. Individual polynomial T compensation guarantees correct response over the whole operating temperature range. XenoCal Solar sensor measures irradiance (W/m²) or radiant exposure (kWh/m²) in the required wavelength bands:

    XenoCal Solar sensor measures irradiance (W/m²) or radiant exposure (kWh/m²) in the required wavelength bands:
    IEC 61215: 280 - 320 nm, 280 - 385 nm
    IEC 61646: 280 - 320 nm, 280 - 400 nm

    The XenoCal Solar sensor may be used to measure any light source used for UV pre-conditioning; it measures fluorescent/UV, metal halide, xenon, gas discharge lamps, or natural solar radiation. For optimum results and precision, a spectral correction factor can be programmed for each specific light source. Four commonly used light sources are factory pre-programmed.
