 Choose these
TC probes for economy. Each thermocouple probe has a 304 stainless steel sheath, 11/4" long x 3/4" diameter nylon handle (except surface probes) 3-ft color-coded PVC cable, and color-coded mini-connector. Choose probes with 20 gauge straight solid core wire cable (holds shape when bent); or coiled cable.Each probe has a characteristic time constant (response time). Five time constants are needed to reach 99% of final reading. See descriptions below for the time constant of each type probe.
