The MTTS Lightmeter 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.

Key Features

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. Spectral response chosen to match wavelength used for Jaundice treatment. Two sided measurement for convenient measurement of double-sided phototherapy devices such as MTTS Firefly.

The Lightmeter features a large, clear display that makes it easy to read under all lighting conditions. The Lighmeter is lightweight and portable. It can be carried around easily and helps health professionals to feel confident in the phototherapy treatment they provide to their patients.

The Lightmeter can be used to measure the intensity of any type of phototherapy device used for the treatment of hyperbilirubinemia in newborn babies, including single-sided and double-sided machines. 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.
