Thermocouple assemblies High temperature assemblies RTD assemblies Thermo well & protection tube Temperature transmitter & controllers Bimetal Temperature gauge Instrument cable		Model 52 Bi - Metal Thermometers Model 32 (3" dial) and Model 52 (5" dial) process grade bimetal thermometers offer the convenience of an all-angle swivel connection. Additionally, the hermetically-sealed case offers protection from weather and dust, and is guaranteed against fogging up. The bimetal helix is coated with a viscous silicone to minimize pointer oscillation and improve temperature transmission.  Model 32 and 52 thermometers are guaranteed for seven years. Case 304 Stainless Steel Dial Anti Parallax, heavy gauge aluminum with white matte finish. External Reset: Slotted hex adjustment Window Fully gasketed glass standard. Lexan, acrylic and shatterproof available. Hermetic Seal Hermetically sealed per ASME B40.3 Standard. Guaranteed not to fog up. SPECIFICATIONS Stem 304 Stainless Steel, TIG welded at tip and case connection. 1/4" diameter standard; 3/8" diameter available. Dampening Helix coated with viscous silicone to minimize pointer oscillation and improve sensitivity (ranges below 500°F). Over Range Temporary over or under range tolerance of 50% of scale up to 500°F (260°C) Accuracy Guaranteed to 1% of full scale (per ASME B40.3 Standard) All Angle Case Simple adjustment of the heavy duty stainless steel harness allows case rotation of 360° and stem variation of more than 180°. Flexible stainless steel bellows sealed at case and stem connector protects the temperature transmission mechanism and guarantees the hermetic seal.
