Rugged Design Features
- All 304 stainless steel exterior parts with instrument glass lens (plexiglass option)
Quick-lock, cam-action bezel ring with heavy duty, heat-resistant gasket seals out moisture to prevent lens icing or fogging and prevents bimetal coil freeze-up in extreme conditions - Built-in over range protection and adjustable pointer are standard
Accuracy
- Accuracy is within 1% of full scale
Easy Reading
- Dials are specially fabricated of low-glare finished metal using a deep drawn design for anti-parallax alignment of pointer to graduation marks.
- High-visibility numerals and graduations also help minimize reading errors.
Fast Response
- Superior heat transfer characteristics, fast response, and consistent repeatability are achieved through the use of a low mass bimetal sensing element.
- Materials and design combine to convert the sensor’s movement quickly and accurately into a dial reading
Easy Dial Rotation
- The replacement configuration provides for easy rotation of its dial face to a right-side up position
- With the bezel and lens removed, a pointed object (such as a ballpoint pen tip) can be inserted in one of the two dial face holes
