Weiss Instruments Bimetal Thermometers

BIMETAL DIAL THERMOMETERS

Weiss offers a complete line of Commercial Bimetal Thermometers in 2", 3"
and 5" dial sizes. All versions are hermetically sealed and silicone dampened
for optimum performance in most industrial applications. A recalibration feature
is standard on the Vari-angle types. Other 3" and 5" dial forms are available
with or without a reset feature for a wider customer choice and savings.

CASE: The entire case assembly is of Type 304 Stainless Steel. To insure a
moisture proof unit, the heavy glass face is securely gasketed with the case
and bezel assembly, hermetically sealed.

STEM ASSEMBLY:The stem and fixed thread connection is fabricated of
stain-less steel. All welded construction insures complete corrosion resistance.
Model BM, RBM and VBM stem diameter is 1/4" and for 2" dials the fixed
thread is 1/4" NPT, 3" and 5" dials are 1/2" NPT.
