The 4meter is used for the determination of the actual level of sources required for effective medical therapy. The tool is useful for both hospital technicians and doctors who want to verify whether the medical equipment can deliver all the functions as designed.
The primary light meter function provides precise measurement of the intensity of the blue light spectrum that is necessary to treat jaundice in infants. This measurement allows health professionals to ensure phototherapy units are working correctly and determine when a phototherapy device or its bulbs need to be replaced.
The device can be used for any phototherapy unit with LEDs, fluorescent bulbs or compact bulbs. When measuring a single-sided phototherapy machine, it will measure the light using the front sensor. When measuring a double-sided phototherapy, the device reads the intensity from both sides, using the sensors on the front and back of the device. It then displays the sum of the values from each side.
