Lightmeter

An easy-to-use instrument to accurately determine the intensity of phototherapy treatment.

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 Overhead Phototherapy V3000, 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.


Quality


By measuring the wavelength spectrum from 450 to 465 nanometers, the Lightmeter gives a reliable irradiance measurement and helps to comply with the American Academy of Pediatrics Guidelines.

Innovation


The Lightmeter provides a quick and accurate measurement of therapeutic light intensity from any kind of phototherapy device to make sure that the patient is receiving the most effective amount of light.

Care


The Lightmeter can also be used as a tool for clinical decision making, allowing the care giver to determine how to position the baby, maximize light exposure, and provide the strongest phototherapy.
