De The head can be rotated 360o and the stem positioning moves over 180o. These thermometers are rugged and preferred by the process, offshore, power, pharmaceutical, and chemical industries. The union connection is 1/2-14 NPT, but others are available. The thermometers may be silicone filled for additional vibration dampening. A variety of lens materials are available including acrylic, polycarbonate, shatterproof and tempered glass. Standard stem diameter, up to 42" long, is .25". Other available stem sizes are .24" (6 mm), .32" (8 mm), and .375" (9.52 mm). |
Specifications
Stem Diameter | .25" standard up to 42" stem; .375" standard over 42" stem |
Connection | 1/2-14 NPT |
External Reset | Easy to calibrate by inserting 1/16" hex wrench into reset opening |
Construction | 304 stainless steel external parts and welded construction; corrosion resistant to most chemicals |
