Ashcroft 30EI60R040 Dial Thermometer 0 250F 3in Stem 1/2in NPT

Ashcroft 30EI60R040 is a 3-inch dial, rear-connected EI Series bi-metal thermometer designed for industrial process temperature monitoring. It reads 0 to 250 °F and uses a 1/2" NPT stem connection with a 3-inch insertion stem, enabling reliable installation in standard process ports while withstanding demanding plant environments. The EI Series features a hermetically sealed case to prevent moisture ingress and coil corrosion, delivering 1% full-span accuracy as part of Ashcroft’s Grade A performance. This model is well suited for monitoring temperatures in piping systems, heat exchangers, and other process equipment where quick, at-a-glance readings are essential and a rear-connection configuration is preferred for compact mounting.
