Type T Thermocouple Probes & Wire  Physitemp
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..- Sizes Available (ga/cm.): 
MT-29/1, MT-29/2, MT-29/3, MT-29/5 MT-26/2, MT-26/4, MT-26/6 MT-23/3, MT-23/5, MT-23/8 
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. 
All above probes are non-isolated. Isolated versions of 23 ga. and larger needles are available for special order.

Flexible Implantable Probes 
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.

General Purpose Probes  Physitemp
 
HT-1 - "Workhorse" probe for liquids, gases, semi-solids. Plastic handle with straight stainless steel shaft. Not good for surface temps. Max. Temp. 400°C. Time constant 0.5 secs. 5 ft. lead. Not Isolated. 
HT-2 - As HT-1 but with 9" shaft. 
BT-1 - For surface temperatures of solids, also for liquids, gases and semi-solids. Probably our best general purpose probe. Welded stainless steel shaft, plastic handle. Tip is .02" diameter bent at right angle to probe to facilitate accurate surface measurement. 5 ft. lead. Immersible. Max. Tip Temp. 240°C. Time constant 0.15 secs. Not Isolated. 
DPT Series- Immersion probes for liquids. #304 stainless steel welded shaft, wooden handle. 5 ft. lead. Max. Temp. 400°C (750°F). Time constant 2 secs. Not Isolated. 
TFT Series - Immersion probes for corrosive liquids. Similar to DPT series but shaft is Teflon coated. Max. Temp. 150°C (300°F). Time constant 3 secs. Isolated. 5 ft. lead. 
PT-6 - Sensor Six-Pack. For multi-point measurements. Inexpensive, flexible, welded sensor beads, tough Kapton insulation, 5 ft. leads. Max. Temp. 400° C. Time constant 0.01 secs. Per package of six. Not Isolated. 
PIT-12 - For permanent installation. 12" lnconel shaft 1/8" dia. Can be formed to fit inside or outside any dia. pipe. Complete with 1/8" NPT compression fitting. 10 ft. leads and quick-disconnect plugs and sockets. Max. Temp. 400°C (750° F). Time constant 3 secs. Not Isolated. PIT-6 - Has 6" stainless steel shaft; otherwise as PIT-12. 
GT-1 - Air and gas probe. 24" #304 stainless steel shaft, wooden handle. 5 ft. leads. For instant readings of temperature gradients in environmental chambers, freezer boxes, etc. Max. Temp. 200°C. Min. Temp. -200°C. Isolated.
