Tempco MTA00805 Type K Thermocouple

The Tempco MTA00805 is a Type K thermocouple probe built for general-purpose temperature sensing. It uses a grounded junction and a standard plug connection. The probe measures 3/16 in by 18 in and operates from 32 to 2,300 degrees Fahrenheit. It suits appliances, ductwork, ovens, packaging and pharmaceutical equipment.

Suits HVAC and process monitoring

This probe fits technicians who need a replaceable Type K sensor for air, surface or immersion readings up to 1,260 degrees Celsius. The transparent jacket and standard plug allow quick visual checks and fast instrument swaps. It is not for buyers who require an ungrounded junction for electrical isolation or a sheath diameter other than 3/16 in.

Grounded Type K junction

The grounded junction places the thermocouple wires in direct contact with the probe tip, giving faster thermal response than an ungrounded design. This single characteristic decides whether the sensor matches the control loop speed and noise environment of the application.

Questions about this item

Does the 18 in probe generate any heat or draw power when running continuously in an oven at 300 °F?

The probe is a passive Type K thermocouple; it produces only a millivolt signal and draws no power, so it adds no heat during continuous use.

What connector or instrument must I already have to read the standard plug on this MTA00805?

You need a meter, controller or data logger fitted with a standard Type K miniature plug socket that accepts the probe's grounded junction.

Will the grounded junction on this 3/16 in probe work reliably with an older panel meter that expects an ungrounded sensor?

A grounded junction can create a ground loop with older ungrounded-input meters; check your meter's manual to confirm it accepts grounded Type K probes before connecting.
