Industrial Bimetal Thermometer, 3 Dial, Back Connect, 6 Stem, -40/120F & -40/50C

Read two scales simultaneously|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 3" diameter dial|Constructed with durable 6" long stainless steel stem|Thermometer features a 40 to 120F (40 to 50C) temperature range|The Cole-Parmer industrial bimetal thermometers feature NEMA 4X/IP66 protection for tough applications. 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 overtemperature 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 40 to 200F (40 to 93C).
