FirstResponder® Spider UV C Sterilizer robot This unit uses shortwave UV C This unit uses shortwave UV C lamps that emit ultraviolet light with the major peak output (~90%) band at 253 This biometric reader controller combines a powerful thermal camera and the latest face recognition algorithm that are accurate and work fast to keep business and people moving with little to no interruption and with full automatic user authentication for a total of 8 dimer inducing germicidal UV C rods that deliver maximum wattage and range The doped fused quartz glass rods of the FirstResponder Spider output in the 254 nm radiation range (which produces negligible ozone levels) but blocks the 185 nm wavelength (which produce higher ozone levels)
