In calibration laboratories, the most important consideration is the quality of the fundamental measurement. ASL's F700 AC bridge technology represents the peak of performance in its class for resistance thermometry measurement and exploits the inherent advantages of AC bridge technology to maintain repeatable measurements of the highest precision under practical operating conditions.

A Few Facts.
The Model F700 is a high accuracy resistance bridge designed specifically for use in resistance thermometry. Its unique AC bridge circuitry eliminates thermal EMF effects to provide you with fast, reliable measurements under a wide range of real operating conditions. A special input guard circuit maintains accuracy by minimizing the effect of probe or cable leakage to ground. The effect of cable and probe reactance is eliminated by an on-board quadrature servo allowing you typically to make measurements up to 100 meters from the PRT. The differential capability allows the resistance of one PRT to be measured against another directly and provides the most accurate comparison calibration technique.

PC Software.
You can use the optional SOFT700 application to provide a virtual instrument display for remote control and temperature versus time graphing. SOFT700 calculates ITS-90 and Callender van Dusen coefficients and performs data acquisition with ASCII file format for easy export.

A True Pedigree.
National standards laboratories around the world require the best instrumentation for their work. The majority of these organizations use ASL's top of the range Model F18 to set the temperature standard in their country. These include 20 out of the 22 members of the international C.C.T. (Consultative Committee of Thermometry). The F700 uses the same AC measurement techniques to provide you unrivalled performance, convenience and flexibility.
