After more than 15 years of service, Kipp & Zonen is replacing its UVS series of radiometers with its next-generation SUV series. Based on the companys SUV5 total ultraviolet (UV) radiometer, the new family of broadband UV radiometers has been tailored to measure specific types of UV radiation including UVA, UVB and UVE, alongside the existing SUV5 total UV version. The SUV series has improved specifications over the UVS, plus the benefits of an RS-485 Modbus digital output and very low power consumption. Due to the all-new optical detection systems for UVA, UVB and UVE, they benefit from a polynomial function temperature correction over a wider operating temperature range, from -40°C to +70°C. The wide voltage range and low power requirements mean that the SUV series is ideally suited for use in remote locations. The Modbus output provides not only the irradiance value in W/m², but also body temperature, power supply voltage, status info, model and serial number plus calibration history. The SUV housings are identical in dimensions to Kipp & Zonens double-dome pyranometers, making it simple to use all radiometer accessories (such as mounting, shading, ventilation and tilting). Finally, the SUV series has no external drying cartridge to inspect, with an internal desiccant that will last at least 10 years. As with Kipp & Zonens other smart instruments, the standard two-year factory warranty will be extended to five years after the purchase is registered through the companys website.
