Main features & Overview


The W6 Series has an improved digital readout utilizing an extra-large five-digit display.

The W6 Series melt pressure gauge provides reliable, maintenance-free, localized pressure indication.

The small capillary tube filled with a special medium isolates the gauge housing from potential thermal damage.
