Industrial temperature monitoring

The Ashcroft 50EI60R dial thermometer is built for process and environmental measurement in mechanical systems. It covers a range of 50 to 550 degrees Fahrenheit and 10 to 290 degrees Celsius. The 5 inch dial provides clear, direct reading for operators and maintenance staff.

304 stainless steel housing

The case and stem use 304 stainless steel for corrosion resistance in harsh media. A 2.5 inch stem reaches into pipes or vessels while the back-mounted 1/2 inch NPT thread allows direct installation without extra fittings. The glass lens protects the scale from impact and chemical splash.

Bi-metal actuation needs no external power

The mechanical sensing element operates without electricity, eliminating signal wiring and power-supply concerns. A NIST-traceable certificate is included for calibration records. The sealed construction keeps dust and moisture out of the movement for stable long-term drift performance.

Questions about this item

What temperature range does the 1/2 in NPT dial thermometer cover in practice?

The thermometer reads from 50 °F to 550 °F (10 °C to 290 °C) through its 1/2 in NPT back connection.

What clearance is needed for the 2.5 in stem and 5 in dial?

Allow at least 2.5 in of insertion depth for the stem and 5 in diameter for the dial face.

How is the NIST-traceable certificate applied during installation?

The certificate accompanies the unit; no on-site calibration step is required — simply mount the thermometer and record the certified readings.
