Model FWT-100 Radiachromic Reader System offers a state-of-the-art
performance for both high and low volume users of Radiachromic film
dosimeters. This reader is fast, accurate and above all easy to
The system consists of a reader head, ISA interface card that plugs
into the inside of your PC and assorted programs. The interface
card and cable are the same as used with the FWT-200 Opti-Chromic
Reader Head, but each system uses different software.
The addition of the computer to the measurement cycle reduces the
complexity of the system. The computer does all the calculations
necessary not only to take a reading but also to reduce the data
and store it for later reference or reporting. It assists the user
by performing the following tasks:
The computer will automatically set the zero of the system as needed.
Beginning with version 2.0 the software is compatible with Win 95/98/ME/2000/XP.
The windows version of the software is a dynamic data exchange (DDE)
server. It provides information on the wavelength and the absorbance
readings for either the 600 nm or the 510 nm analysis wavelengths
to DDE client programs such as Microsoft Excel or Access. A sample
Excel spreadsheet is included to illustrate how data may be accessed
by Excel's DDE functions.
The Radiachromic head has a single slot for the film. Place the
film in the slot using round tip tweezers and the computer will
signal when the reading is complete. It is not necessary to release
the film from the tweezers. This makes the measurements not only
easier but much faster than instruments with separate film holders.
The Model FWT-100 Radiachromic readers represent an advanced system
for measuring Radiachromic Dosimeters. With this new system, accurate,
repeatable measurements are made faster than ever before.
