BI-METAL THERMOMETERS

Case: Sturdy, corrosion resistant series 304 Stainless Steel case and bezel.
Crystal: Optically clear, strong glass, gasketed to maintain weather-tight integrity is standard.
Stem: 304 Series Stainless Steel, welded at tip and case connector to prevent leakage. ¼" (6.35mm) diameter is standard.
Hermetic Seal: Hermetically sealed per ASME B40.3
External Reset: A slotted-hex adjustment head offers screwdriver or wrench use to field calibrate the thermometer.
Bi-Metal Element: An extremely responsive temperature sensing helix which has been carefully sized and tested, heat treated and aged to relieve inherent stresses and unsure continued accuracy.

Dampening: Bi-Metal helix is coated with a viscous silicone to minimize pointer oscillation and to improve temperature transmission.
Immersion: For accurate temperature readings, immerse stem a minimum of 2" (50mm) in agitated liquids or 4" (100mm) in moving air or gas.
Over Range:Temporary over or under range of 50% of scale up to 260ºC or 500ºF will not affect the instrument accuracy.
Accuracy: Guaranteed to be accurate to within 1% of full scale (Grade A per ASME B40.3). (The American Society of Mechanical Engineers issued a new standard for Bi-Metal Thermometers in 1990 referred to as ASME B40.3).
Standard Connection is ½" Male NPT.
