The Olympic Bili-Meter has long been recognized as the standard of accuracy for measuring irradiance during neonatal phototherapy - used for almost 20 years in thousands of nurseries worldwide. Now the new Model 22 Bili-Meter offers the same trusted accuracy along with several improved features, including memory. When using previous model Bili-Meters, it was necessary to memorize the final reading before releasing the button and shutting the instrument off. With the new Model 22 Bili-Meter, however, when you release the button, your final reading remains locked on the display for 30 seconds. This gives you time to put the Bili-Meter down and chart your reading without having to memorize it. Your job is made easier and faster, and the possibility of memory error is eliminated. To take a new or repeat reading, simply press and hold the button and the previous memory is erased.

Reliable, Reproducible Measurements
The key to the Olympic Bili-Meters accuracy is the precision optical system. The sensor has a dome diffuser to minimize angular sensitivity. Behind the diffuser a specially designed dichroic filter transmits only the narrow wavelengths of blue light that principally affect bilirubin. Another filter blocks the infrared, and a sensitive, blue-enhanced diode detects radiation. To this laboratory quality optical system, the new Model 22 Bili-Meter has now added microprocessor electronics for improved linearity and reliability and memory.


Measure All Phototherapy Lights
The Model 22 Bili-Meter is available with either or both of two sensors. Both sensors measure in standard units of microwatts per square centimeter per nanometer - range 0.1 to 150.0 - and the same spectral region of 425-475 nanometers.
