Comparing the 451P and the RaySafe 452

Hi, I'm Ed Brand, RaySafe business development manager. Today I'm going to show you the physical differences between the Victoreen 451 and the RaySafe 452, both manufactured by Fluke Biomedical. The 452 comes in three versions, the air kerma version, using the gray lid, the ambient dose version using the yellow lid, and the full version using both lids plus the ability to use the GM tube as a standalone counter. The 452 has a rechargeable battery and stores data from up to 4000 exposures, it has a USB port in the side that can be used to charge the battery and communicate with a PC, the LCD is easy to read and displays all parameters that are measured as well as allows you to navigate through the menu system, change units, set alarms, turn on and off sound, etc. The technology included in the 452 is kind of unique, it's not an ionization chamber, it has an array of diodes and scintillators, in this area, and in the center, it has a pancake GM tube.
