CUSTOM-CALIBRATED DIAL

The dial of each W&T Barometer is individually calibrated over its complete range.

Custom dial calibration, precision mechanism construction, and match dials and mechanisms give accuracies to 0.1% and sensitivities to 0.01% of full scale.

DURABLE AND CONVENIENT

Although sensitive, W&T Barometer mechanisms are not fragile; they resist damage during on-the-job handling.

EXCELLENT READABILITY

W&T Barometers have scales from 16 to 35 inches long. Long scales mean many graduations can be used to cover the full range. In the highest range (13 to 30.5 in. Hg), the minimum graduation represent 0.02 in. Hg. With the knife-edge pointer, this allows readings to better than 0.02% of full scale. A mirror ring eliminated parallax errors

PRECISION CONSTRUCTION

A small sensitive capsule responds to minute pressure changes. The almost frictionless linkage contains flexures and jewel bearings and is not lubricated. Low inertia parts throughout gives W&T Barometers fast response speed and high sensitivity.
