Fine - Gauge, Bare - Wire Thermocouple Probes

Fine - gauge bare - thermocouple wire probes with 0.005" and 0.010: diameters provide quick temperature measurements (time constant typically less than 0.3 seconds). Larger probes with 0.020" and 0.032" diameters ensure long - term durability but have slower response time (time constant typically 1.5 seconds or less). Probes feature beaded junctions and 12" leads. The negative lead is slightly shorter than the positive lead for easy identification. Probes come in packs of five.

Thermocouple Miniconnector Plugs

Miniconnector plugs can be wired to your bare wire thermocouple probes. Attach to probes when using a meter that accepts miniconnector inputs.

New Economical PVC-Insulated Probes

PVC insulated probes are ideal for quick readings in hard to reach areas. With exposed junctions, probes have a time constant of 3 seconds; response time is 15 seconds. Small-diameter 24-guage (0.020" dia) wire probes are 3 -ft long. Probes include rubber strain relief and ANSI color-coded miniconnector.

8515-00	J	-310 to 221�F (-190 to 105�C)
8515-01	K	-418 to 221�F (-250 to 105�C)
8515-02	T	-418 to 221�F (-250 to 105�C)

New High - Temperature Thermocouple Probes

Use new high temperature probes to take the temperature in tight places. Bend probes around pipe diameters as small as twice the sheath diameter to easily determine your pipe temperature. Probes are tightly packed with powdered MgO in 12 to 25"l sheaths. Type J and type K probes feature INCONEL� sheaths; type T probes feature 316 stainless steel sheaths. Probes include 3-ft stranded 24-guage (0.020" dia) fiberglass wire with stainless steel overbraid.
Note: Type J exposed junction thermocouple probes are not recommended for use with aqueous solutions.
