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.  1/4" (6.35 mm) 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 insure continued accuracy.
• Dampening:  Bi-Metal helix is coated with a viscous silicone to minimze 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 260C or 500F will not affect the instrument accuracy.
• Accuracy:  Guaranteed to be accurate to within 1% of full scale (Grade A per ASME B40.3).
• Standard Connection:  1/2" Male NPT.
