This Stampede Stills 2" temperature gauge with 1/2" NPT LF Brass Thermowell with set screw will make a nice addition to a still or to an extra spot you might want to measure a temperature.
The thermowell is sealed and can be used threaded in to a fitting or soldered directly into place.
The custom temperature gauge measures in easy to read Centigrade and Fahrenheit scales.
*Note: To add this to a current project, there is a $10 labor charge that will be added.
