Phototherapy exposure in this range is used in the treatment of hyperbilirubinemia in newborn children. The DALE40 provides continuous measurement of irradiation by simply placing the detection probe under the phototherapy light (fluorescent lamps only). In addition to verifying output power, the DALE40 saves costs by eliminating premature replacement of lamps. Light measurement is according to the percent response given the wavelength characteristics curve. The detector probe, included with the unit, has a wide angle lens which matches the cosine receiving function of human skin. Measurements are taken in µW/cm2, with a range of 0-1999. This unit of measurement can be compared directly to other units of measurement.   Features Large LCD Accurate to ±5% of full scale Spectral range of 429-473 nm Complete portability   Standard Accessories Case Operator's manual Specifications     Spectral range 429 - 473 nm (max. 97% response at 453 nm) Measurement range 0-1999 µW/cm2 Resolution 1 µW/cm2 Probe Lens matches the cosine receiving function of human skin Power 9 V battery; an arrow appears on display for battery replacement; 150 continuous hours operation Weight 8.8 oz (250 g) Dimensions 5.7" x 3.1" x 1.5"  (14.5 cm x 8.0 cm x 3.8 cm) Back to top Back to products list
