"SKY BLUE" Fill (SB) Environmentally Safe Models are filled with a mercury-free Blue Liquid. SB Models are available in 9" Cases, with either 3-1/2" or 6" Stem Lengths, Ranges up to 300°F. Mercury filled models are still available.
All Angle Adjustment: (pictured at right) Just two screws permit cases to be rotated 180° and stems to be positioned in 10° increments. Users can "infinitely" adjust Economy Line Industrial Thermometers to virtually any viewing angle required.
Easy Readability: Standard Lens front glass tube is "Red Reading" Mercury-Filled or Sky Blue Fill. Compact, yet visible 9" (229mm) Plastic or Aluminum, or 12" (305mm) Aluminum (only) cases, fitted with a "V" shaped white aluminum scale graduated with bold black lines and numerals.
Accuracy: Economy Line Industrial Thermometers are calibrated against standards traceable to the National Institute of Standards and Technology (NIST) and are guaranteed accurate to ±1 scale division.
Construction: User selection of either tough, black-finished molded high temperature Plastic Case (9FL Models) or extruded, black-finished Aluminum Case (9AL or 12AL Models). Glass crystal, machined Brass Swivel Nut, and cast aluminum stem and seat are standard on all 3-1/2" stems.
Connection Assembly: Tapered Bulb Chamber allows maximum metal-to-metal contact with matching tapered thermowell for fast response and increased accuracy. Brass Swivel Nut is industry standard 1-1/4"-18 UNEF thread.
Range and Stem Length Selection: Full selection of Fahrenheit or Dual F & C Range scales available from -40 to 400°F (-40 to 204°C). Stock stem lengths are 3.5"(89 mm), 6"(152 mm), 8"(203 mm), 9"(229 mm) and 12"(305 mm).
Air Duct Construction: Air Duct Models feature a super-sensitive bare bulb protected by a 3/4" diameter perforated aluminum bulb guard. This design allows exposure to circulating air while still protecting the glass tube from any impact.
