Model 1980 Gauges with Brass Internals

DESCRIPTION
The Model 1980 4-1/2" process gauge has a PET turret
style case for chemical and petrochemical processing
applications. The PET material gives this case superior impact strength and a broad spectrum of chemical
resistance. This model is available with wetted surface
material in brass/phosphor bronze. They are available
dry or liquid filled from the factory or your local stocking
distributor and come with a liquid fill kit, or the E-Z Fill
design to facilitate filling in the field without special tools.
The Model 1980 4-1/2" SOLFRUNT gauges are supplied in 26 vacuum, compound, and pressure ranges
from 30" Hg vacuum through 11,600 psi. The low-connected PET turret case can be easily liquid filled in the
field using the appropriate conversion kit.
Span adjustments can be accomplished from rear of
case without disturbing the gauge internals. Pointer adjustments are easily made by removing ring and window.
