9FL/9FLSB Economy Industrial Thermometer
• Flex Angle Adjustment: 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 (red spirit-fill or Sky Blue fill option).
Compact, yet visible 9” (229mm) or 12” (305mm) cases are 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 case material (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 3.5” stems. Brass stem and seat on all other stem lengths.
• 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 NEF thread.
• Range and Stem Length Selection: Full selection of Fahrenheit or dual, Fahrenheit/Celsius
range scales available from -40°F (-40°C) to 550°F (290°C). Stock stem lengths are 3.5” (89mm),
6”(152mm), 8”(203mm), 9”(229mm), and 12” (305mm).
• Air Duct Construction: Air Duct Option Models (9FLAD and 9ALAD) feature a super-sensitive
bare bulb protected by a 3/4” diameter perforated brass bulb guard. This design allows exposure
to circulating air while still protecting the glass tube from impact during shipping, installation, or
use. See detail illustration, page 3.
• NEWEnvironmentally Safe Models: “Sky Blue” models are filled with a non-toxic, mercuryfree
liquid. SB models are available in 9” cases only, 3-1/2” and 6” stem lengths up to 300°F.
