Interchangeable Immersion Type Extension Arms

The PYRO Model SDT141S extension arm is an Industrial grade and constructed from rugged 5/8" diameter brass tubes with protective chrome plating. The extension arm also incorporates a saw tooth knuckle adjustable angle near the thermocouple connector. This angle can be adjusted in increments up to a 90° angle for immersion temperature measurements. The standard overall length of the extension arm is 32 inches.  Custom lengths or extension arms are available up request, consult factory
