PMA 2104 Underwater UVB Detector

The PMA2104 detector provides precise measurement of biologically weighted ultraviolet radiation from sunlight and artificial light sources, also known as sunburn ultraviolet radiation (SUV). Its spectral response is close to the erythema action spectrum.

Technical parameters:

• Spectral response Follows erythema action spectrum Figure 1
• Angle response 15% for angles<50°
• Range 20 [MED/Hr], 1,17 [µW/cm2]
• Display resolution 0.001 [MED/Hr], 0.01[µW/cm2]
• Operating environment 32 to 120 °F (0 to +50 °C) no precipitation
• Temperature coefficient 1% /°C for solar radiation
• Cable 35ft, (10.6m) Waterproof 7pin keyed
• Diameter W/O Cable 5.5" (139.7 mm)
• Height 3.5" (88.9 mm)
• Weight W/O Cable 48 oz. (1360 grams)

Key Features:

• The PMA2104 is a detector for UVB measurements through fresh or salt water. The values measured by the PMA2104 are comparable to those measured by a spectroradiometer immersed in water.
• The detector is waterproof and can be submerged to 100m. Its housing can withstand harsh environments and is easy to operate. There are two #10-32 taped holes on the bottom of the housing to help users install accessories to fix the probe position. The weight of the detector is also suitable for sinking.
