Type J thermocouple probe with mini plug measures air, gas or liquid from -346 °F to 2,913 °F
This Dayton thermocouple probe uses a grounded Type J junction with a mini plug connector. It is built for industrial temperature measurement in air, gas or liquid media. The 1/8 inch by 6 inch probe fits 1/4 inch and 1/8 inch MNPT process connections. It suits technicians who need a compact sensor for direct immersion applications.
The probe operates from -346 degrees to 2,913 degrees Fahrenheit, which is -210 degrees to 1,200 degrees Celsius. A 6 inch cable links the probe to the mini plug, so the instrumentation must be positioned close to the measurement point. The grounded junction gives fast response but requires the meter to accept grounded inputs. The fixed cable length and mini plug format restrict use to nearby panel meters or handheld devices.
This probe replaces a damaged or drifted Type J sensor that uses the same mini plug and MNPT thread sizes. The upgrade is worth it when the old probe shows slow response, physical damage or calibration failure. It is not for applications that need an ungrounded junction, a longer cable run, a different thermocouple type or a larger sheath diameter.

This probe is grounded, so the junction contacts the sheath for faster response in air, gas or liquid; choose ungrounded only if you need electrical isolation.
The sheath and Type J calibration are rated to 1 200 °C, but continuous use near that temperature will age the iron-constantan wires faster than at lower temperatures.
The mini plug mates only with Type J mini sockets, so the probe works with meters or controllers that accept that specific connector and calibration.
