Purpose & Audience
The Tempco MTA01204 is a Type J thermocouple probe designed for temperature sensing in appliances, ducts, food and beverage lines, HVAC systems, ovens, packaging machinery and pharmaceutical equipment. It suits technicians and engineers who need a reliable sensor for process monitoring in those specific environments.
Interface Limits
The probe uses an ungrounded junction with a terminal-block connection and a 1/2 inch MNPT process fitting. Its calibrated range spans 32 to 1,400 degrees Fahrenheit or 0 to 760 degrees Celsius, so measurements outside that window are not supported by this model.
Compatibility Check
Verify that your instrument accepts a Type J thermocouple input and can terminate wires at a terminal block. Confirm the 1/2 inch MNPT thread matches your mounting port and that the 1/4 inch by 24 inch probe dimensions fit the insertion depth required by your application.

Questions about this item
Should I pick a Type J probe for my HVAC duct work or would another type suit it better?
Type J covers 32 to 1,400 °F (0 to 760 °C) and is standard for HVAC ducts, ovens and food processing, so it matches the listed applications.
What does the 1,400 °F upper limit mean when the probe sits inside a running oven?
The probe is rated to 1,400 °F (760 °C); above that temperature the Type J junction can drift or fail, so keep the process temperature within the stated range.
How does the 1/2 in MNPT terminal block connect to my control panel?
The 1/2 in MNPT fitting screws directly into a matching female port on the duct or panel, and the terminal block provides screw terminals for the extension wires.
