Meet the JEL2400. This low-profile, high-intensity germicidal detector has detectors heads configured specifically for the 254 nm wavelength or 365* nm wavelength and offers research-grade quality at an affordable price. The detectors narrow bandwidth at the center wavelength of 254 nm helps facilitate the measurement of germicidal effectiveness at 254 nm from high intensity germicidal UV sources.
