A bilirubinometer is an instrument which uses spectrophotometry to determine the levels of bilirubin present in the blood. This level is expressed as a measurement called TSB or total serum bilirubin. The primary application for bilirubinometers is in neonatal and pediatric medicine, where they are used to diagnose or assess the risk of conditions including bilirubin encephalopathy. Testing for jaundice, however is the most common use for these instruments. This Bilirubinometer runs on 120VAC at .8 amps 60 Hz. The unit is about 15 long by 8-1/2" wide by 9-1/2" tall. Unit powers up and appears to be in working condition, but we don't have any way to confirm it calculates correctly. Only have a few!
