Including ultraviolet UVA band (320nm-380nm), UVB band (280nm-320nm), and UVC band (200nm-280nm). UVA band is mainly used for light curing, lithographic exposure, UV light source, integrated circuit lithography industry. UVC band, also called short-wave ultraviolet sterilization. UV germicidal lamps emit UVC UVC is. LS125 multi-probe UV radiation meter, digital probe, plug-in design, intelligent judgment probe instrument models. And it can support five different UV probe. A: LS125 host parameters 1. Instrument Weight: about 320 g 2. Host Size: length 125mm × width 72mm × height 14.5mm 3. Battery: 2 AAA alkaline batteries. 4. Probe Connection: push-pull self-locking (snap) II: parameters supported LS125 LS125 measurement needs of the current probe according to different industries, offers five probes choose: 1: P254 probe 1) Spectral response: 230nm-280nm; λp = 254nm 2) measuring range: 0 -200000 uW / cm2 3) Resolution: 0.1μW / cm2 4) Accuracy: ± 10% 5) test light hole diameter: ￠ 10 6) Probe Dimensions: Diameter 46mm × thickness 16.1 mm 2: P365L probe 1) Spectral response: 260nm-400nm; λp = 365nm 2) Measuring range: 0-200000uW / cm2 3) Accuracy: ± 10% 4) Resolution: 0.1 uW / cm2 5) test aperture diameter : ￠ 10 6) Probe Dimensions: Diameter 46mm × thickness 12.2mm 3: P420L probe 1) Spectral response: 340nm-420nm; λp = 395nm 2) Measuring range: 0-200000uW / cm2 3) Accuracy: ± 10% 4) Resolution: 0.1 uW / cm2 5) test light hole diameter: ￠ 9.2 6) Probe Dimensions: Diameter 46mm × thickness 14.6mm 4: E365 Probe 1) Spectral response: 320nm-400nm; λp = 365nm 2) Power Range: 0 - 10000mW / cm2 3) energy measurement range: 0 --- 999999mJ / cm2 4) Accuracy: ± 10% 5) Resolution: 0.1 mW / cm2 6) test light hole diameter: ￠ 9.2 7) Probe Dimensions: Diameter 46mm × thickness 14.6mm 5: E395 Probe 1) Spectral response: 340nm-420nm; λp = 395nm 2) Measuring range: 0-20000mW / cm2 3) energy measurement range: 0 --- 999999mJ / cm2 4) Accuracy: ± 10 % 5) Resolution: 0.1 mW / cm2 6) test light hole diameter: ￠ 9.2 7) Probe Dimensions: Diameter 46mm × 14.6mm thick
