The PMA2104 detector can accurately measure the bioweighted ultraviolet radiation of sunlight and artificial light sources, also known as Sunburn Ultraviolet Radiation (SUV). Its spectral response is similar to the spectrum of erythema.

Technical parameters:

• Spectral response Follow erythema action spectrum Figure 1
• Angle response 15% for angles<50 °
• Range 20 [MED/Hr], 1,17 [µ W/cm2]
• Display resolution 0.001 [MED/Hr], 0.01 [µ W/cm2]
• Operating environment 32 to 120 ° F (0 to+50 ° C) no preparation
• Temperature coefficient 1%/° C for solar radiation
• 35ft cable, (10.6m) Waterproof 7pin keyed
• Diameter W/O Cable 5.5 "(139.7 mm)
• Height 3.5 "(88.9 mm)
• Weight W/O Cable48 oz. (1360 grams)

Main features:

• PMA2104 is a detector used for UVB measurement through freshwater or saltwater. The value measured by PMA2104 can be comparable to the value measured by a spectrophotometer immersed in water.
• The detector adopts a waterproof design and can be submerged up to 100m underwater. Its casing can withstand harsh environments and is easy to operate. There are two # 10-32 taped holes at the bottom of the casing, which help users install fixed probe position attachments. The weight of the detector is also suitable for sinking.
