Ashcroft 30EI60R Bi-Metallic Back 6 in Dial Thermometer

Bi-Metallic Dial Thermometer

The Ashcroft 30EI60R is a back-connected dial thermometer built for environmental and mechanical temperature monitoring. Its bi-metallic sensing element operates across a range of 50 to 550 degrees Fahrenheit and 10 to 290 degrees Celsius. A 3-inch dial provides clear readings, while a 304 stainless steel housing and glass lens protect the movement in demanding settings. A 6-inch stem with 1/2 inch NPT threads allows direct installation into process connections.

Suited for industrial process checks

This instrument suits technicians and plant operators who need a durable, direct-mount thermometer for pipes, tanks or vessels where a rear connection is preferred. The included NIST-traceable certificate supports quality-system requirements. Buyers who require a digital display, adjustable stem angle, or a different temperature span should evaluate alternative designs. The fixed back connection limits flexibility where a bottom or adjustable mount is needed.

Temperature span and installation fit

The 50 to 550 degree Fahrenheit range covers common steam, hot water and process heating duties with comfortable headroom above typical operating points. The 6-inch stem reaches into larger pipe diameters or insulated walls without excessive immersion length. At the upper limit near 290 degrees Celsius, sustained exposure may reduce service life compared to lower-temperature service. The 304 stainless housing resists corrosion in many environments but is not rated for highly aggressive chemical attack.
