Ashcroft 7MA-15421-016 Bimetal Thermometer 1/2 NPT

Ashcroft 7MA-15421-016 is a bimetal dial thermometer with a 1/2" NPT process connection. It provides temperature readings from 50 to 550°F, with a Fahrenheit-scale dial. The instrument uses a bi-metal element to translate temperature changes into pointer movement on the calibrated dial for direct, at-a-glance monitoring. The 7MA series is designed for threaded installations in process equipment and piping, allowing mounting in ports with standard 1/2" NPT threads. This model's compact connection size makes it suitable for tight spaces where accurate temperature indication is required without external power or complex electronics. The combination of a simple mechanical sensing element and an easily readable dial helps maintenance teams quickly verify process temperatures and detect deviations.
