Product Identity
The Tempco MTA00802 is a Type J thermocouple probe built for general-purpose temperature sensing in appliances, ductwork, food and beverage lines, HVAC systems, ovens, packaging equipment and pharmaceutical processes. It suits technicians and engineers who need a grounded junction with a standard plug and mating jack for direct connection to compatible instrumentation.
Thermals and Power
The probe operates from 32 to 1,400 degrees Fahrenheit, which is 0 to 760 degrees Celsius, covering the full Type J range for the listed applications. A grounded junction provides fast thermal response while the transparent sheath allows visual inspection of the sensing tip during installation and service.
Build Integration
The 3/16 inch diameter by 12 inch long sheath fits into standard process fittings and duct openings without requiring oversized ports. The standard plug and mating jack connect directly to existing Type J wiring, so no special adapters or signal conditioners are needed for basic temperature monitoring tasks.

Questions about this item
How do I install the grounded Type J probe into a duct, and which step is often missed?
Slide the 3/16 in x 12 in sheath into the duct fitting and tighten the compression nut so the grounded junction contacts the metal wall; the step often missed is verifying continuity between the probe sheath and the standard plug before powering the controller.
What maintenance or replacement will the Type J thermocouple need later?
The grounded junction can drift after repeated thermal cycling between 32 and 1,400 degrees F, so plan to recalibrate or replace the probe when readings shift beyond your process tolerance.
What limit appears first during sustained high-temperature use?
The 1,400 degrees F (760 degrees C) upper temperature rating of the Type J element is the first limit reached under continuous operation.
