We offer a wide range of hand held thermocouple sensors to suit a variety of applications. Depending on the thermocouple type, these hand held thermocouple sensors can be supplied with a 3, 6, 16 or 32 ft (extended) coiled lead and a miniature flat pin plug which makes them suitable for all connection to a hand held instrument as well as most other brands of readout device. They can also be connected to other instrumentation by using thermocouple extension cable and an appropriate connector.

See detailed information on how a thermocouple works. including ionformation on the seebeck effect and thermocouple generated voltage (emf).

Style	Description	Tip Image
5AA	General Purpose Thermocouple Probe Mineral insulated thermocouple with a stainless steel sheath. Insulated hot junction. The tip and sheath may be operated up to 2010ºF and the sheath may be bent. Can be made to any length in a choice of 0.125", 0.188" or 0.250" diameter.
5BB	Spring Loaded Surface Probe This sensor probe has a ribbon style butt welded sensing tip which allows a fast response when placed upon a solid surface. The tip is rated to 750°F and the handle to 275°F. Sheath: 0.250" dia x 6.5" long (from handle to tip)
5CC	Heavy Duty Spring Loaded Surface Probe A robust version of style 5BB with a larger butt welded ribbon junction. Whilst stronger, the response time is slightly slower; however, in most applications it is perfectly acceptable. The tip is rated to 750°F and the handle to 275°F.
5DD	Spring Loaded Surface Probe with 90º Bend As style 5BB, but the sensing tip is positioned at a right angle for difficult to reach applications. The tip is rated to 750°F and the handle to 275°F. Sheath: 0.250" dia x 7.7" long (5.5" to start of bend).
5EE	Heavy Duty Spring Loaded Surface Probe with 90º Bend A robust version of style 5CC with a larger butt welded ribbon junction. Whilst stronger, the response time is slightly slower; however, in most applications it is perfectly acceptable. The tip is rated to 750°F and the handle to 275°F.
5FF	Fast Response Air/Gas Thermocouple This style is ideal for measuring the temperature of air or gas flows as it has a perforated tip to allow for almost instant measurements. The stem is rated to 1450ºF and the handle to 275ºF. Sheath 0.190" diameter x 6.1" long (from handle to tip).
5GG	Needle Penetration Sensor This probe thermocouple can be used for penetrating semi solid materials (food, plastics, rubber etc.) as it has a sharp sensing tip. The stem is rated to 1450ºF and the handle to 275ºF. Can be made in either 0.078" or 0.196" diameter up to 3.5" or 11.4" long respectively.
5HH	Heavy Duty Needle Penetration Sensor Probe All stainless steel construction, this sensor is similar to the standard Needle Penetration Sensor, however due to the 90º cable exit, the sensor can be hammered into hard surfaces such as frozen food. Can be made to any length up to 6" , 0.250" diameter.
