Ashcroft 50EI60R Bi-Metallic Dial Thermometer 0-250°F 2.5in Stem

Precision Temperature Instrument

The Ashcroft 50EI60R is a bi-metallic dial thermometer built for professionals who need reliable local temperature readings in industrial or mechanical systems. Its stainless steel housing and glass lens withstand harsh environments while the 5 inch dial provides clear visibility at a distance. The 1/2 inch NPT back connection allows direct installation into process piping or vessels. This tool suits technicians and engineers who value durable, analogue instrumentation.

Interface And Range Limits

The thermometer covers 0 to 250 degrees Fahrenheit and -20 to 120 degrees Celsius with a fixed 2.5 inch stem length that determines insertion depth. Accuracy depends on proper immersion in the media being measured; the stem must reach the process temperature zone for valid readings. The 1/2 inch NPT thread restricts mounting to compatible fittings, and the back connection orientation may limit installation in tight spaces. No electrical output or data logging capability is included.

Upgrade Considerations

This model replaces basic uncalibrated dial thermometers where documented accuracy is required for quality or safety programmes. The included NIST-traceable certificate supports audit trails without sending the instrument to a third party lab. The jump is worthwhile when regulatory compliance or process validation demands certified calibration out of the box. It does not suit applications needing remote monitoring, alarms, or digital integration with control systems.
