The VSR144 is an industrial version of the 300144. This device has the stability that is inherent in foil but does not offer the tight
match, TCR, or TCR tracking of the 300144. This product is quite satisfactory for most industrial purposes and should be
considered when the total performance of the 300144 is not necessary.
