Precision Temperature Probes

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.

MT-4 - Similar to MT-29/1 but has blunt tip. Good for instant skin and surface temperatures, liquids. Time constant .025 secs. Not isolated.

ICT-4 - For use on integrated circuits and other micro specimens. 0.013” dia. straight stainless steel shaft; slightly protruding sensor bead to facilitate temperature probing. 5” tubular handle fits micro- manipulators. Max. Intermittent Temp. 200°C, continuous use 100°C, Time constant 0.25 secs. 5 ft. lead. Not Isolated.

MT-29/1B - Insect Probe - Similar to MT-29/1 but sensor is welded into tip for max. heat transfer. Designed for high accuracy on extremely small specimens such as insects, seeds, etc. Max. insertion depth 1/8”. Time constant 0.015 secs. 5 ft. lead. Max. Temp. 150°C. Other sizes made to special order. Not Isolated.

IT Series. Implantable in semi-solids and tissue with needle (supplied). Also for immersion in various solutions and rectal temperatures of small animals. Totally sheathed in chemical resistant Teflon. Quite rugged. Max Temp. 150°C. Isolated. Type # designates needle gauge. (Or one gauge smaller in thin wall).

IT-23 - For ultra fast measurements and for use on micro-size specimens. Sensor lead only 0.009” dia. Tissue implantable with 23ga. needle (supplied). Rather fragile. Max. temp. 150°C. Time constant 0.005 secs. 3 ft. lead. Teflon coated. Isolated.

IT-1E - As IT-18 but sensor bead exposed. Combines the ultra-fast response of IT-23 with the Teflon sheath strength of IT-18. Time constant .005 secs. Isolated.
