Type T Thermocouple Probes & Wire
Needle Microprobes

Fast-response needle probes for instant readings in tissue, semisolids, liquids. Also for very small specimens, powders and materials. Needle tip is sealed to ensure only stainless steel contacts specimen. Max. temp. 200°C. 5 ft. lead. Smallest microprobes give fastest reading. Short probes are easier to insert and last longer. Type #'s indicate needle gauge and needle length in cm..-

Type T Thermocouple Wire

0.1°C accuracy in the following sizes: 30ga, 36ga, 40ga, 44ga

Most thermocouple wire used in the manufacture of sensors is "Special Limits" wire which, to meet NIST standards, must be accurate to 0.5°C in the range 0-50°C. This means that even with most sophisticated electronics, the best possible accuracy for the system is 0.5°C....
