MTTS Lightmeter

The MTTS Lightmeter 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 Lightmeter was developed for use with the MTTS Firefly and MTTS Colibri Overhead Phototherapy, but it can be used for any phototherapy unit with LEDs, fluorescent bulbs or compact bulbs. When measuring a single-sided phototherapy machine, the Lightmeter will measure the light using the front sensor. When measuring a double-sided phototherapy, the MTTS Lightmeter 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.
