The 50H series of Dial Thermometers feature leak-proof construction and smooth, bendable stiff armor for easy installation into jacketed tanks, agitated vessels, and storage tanks where a rigid stem thermometer cannot be used. Palmer filled system Dial thermometers offer uncompromising accuracy. Engineered to provide a long service life, direct drive dial thermometers are used in many different applications. The stainless steel bezel ring and lens provide a weather-tight seal.
Palmer Dial thermometers feature a direct drive double wound bourdon coil. The pointer shaft is operated directly from the center coil in this design, eliminating the conventional sector and pinion movement and the multiplying mechanism, both subject to wear and tear and leading to inaccuracy over time. Our direct drive double wound bourdon coil is a unique feature resulting in an extremely responsive temperature indicator that will maintain accuracy for years. Every Palmer Dial thermometer has an easy to read scale, constructed with high contrast black numerals, graduations, and pointer to minimize reading errors.
