"• The benefits of a liquid-filled case in a silicone-free dry configuration • Dampened movement• More economical than silicone gauges• Greater temperature range than a silicone-filled gauges• Anti-parallax dial for accurate readings• Eliminate the risk of a leaking case and cross-contamination• Hermetically sealed per ASME B40.3 standard to prevent fogging and protect against tough environments• Rugged 304 stainless steel construction with a clear glass lens• Recalibrate using the external reset screw 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). | Measured stem length from the top of the threads to the bottom tip of the stem. Stem dia is 0.25\"; threaded connection is 1\/2\" NPT(M). All thermometers meet or exceed ASME B40.3 standards. | Maximum environmental temperature for glass lens thermometers is 500degF (148degC)."
