Industrial Silicone-Filled Bimetal Thermometer, 5 Dial, Back Connection, 2 Stem, 0/250F & -20/120C

Improve readings and response times with silicone-filled dial|Silicone-filled for reduction of pointer flutter on high vibration applications Easy-to-read dual F/C scales provide enhanced flexibility Anti-parallax dished dial for superior readability Durable all-welded stainless steel construction for tough environments Prevent dial fog, entry of moisture, interior corrosion, and coil freeze up with hermetically sealed case Rugged NEMA 4X/IP66 protection Recalibrate using the external reset screw 1% full-scale accuracy according to ASME B40.200 (B40.3 Grade A)|Designed with 5" diameter dial|Constructed with durable 2.5" long stainless steel stem|Thermometer features a 0 to 250F (20 to 120C) temperature range|The Cole-Parmer silicone-filled industrial bimetal thermometers feature NEMA 4X/IP66 protection for tough applications. Designed for the most severe vibration conditions, the silicone is used to dampen and lubricate internal parts, enhancing readability and lifespan. Silicone-filled thermometers offer superior performance that will hold up to the toughest vibration applications. The lens material is constructed of polycarbonate due to the expansion properties of silicone. Accuracy is 1% full-scale when stem is immersed 2" in liquids or 4" in gases (immerse models with a 2.5" stem length 2" in gases). Stem length is measured from the top of the threads to the bottom of the stem tip. Stem diameter is 0.25 with a NPT(M) back connection. Maximum over temperature for thermometers with a max temperature of 250F is 100% of span, and thermometers with a max temperature of 550F is 50% of span. The ambient temperature range limits are 40F to 150F (40C to 65C).
