		Needle Microprobes Fast-response needle probes for instant readings in tissue, semi-solids, liquids. Also for very small specimens, powders and materials. Needle tip is sealed to ensure only stainless steel contacts specimen. Max. Temp. 200 °C. SFT. 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 0.025 s. Not isolated. All above probes are non-isolated. Isolated versions of 23 ga. and larger needles are available for special order.
		Flexible Implantable Microprobes 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. lsolated. Type # designates needle gauge (or one gauge smaller in thin wall). Type Dia. Time Constant Lead Length MT-23 23 ga (.25”) .15 s 3 ft. MT-26 26 ga (.18”) .1 s 3 ft. MT-29 23 ga (.13”) .025 s 1 ft
		IT-23 - For ultra fast measurements and for use on micro-size specimens. Max. diameter at tip 0.011 ". Tissue implantable with 23 ga. needle (supplied). Rather fragile. Max. Temp. 150 °C. Time constant 0.005 s. 3 ft. lead. Teflon™ coated. Isolated.
		IT-IE - 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 s. Isolated.
		MT-D - Fast response surface probe for locating inflammation, arteries, etc. Also for dental use. Stainless steel. 5 ft. lead. Max. Temp. 200 °C. Time constant 0.025 s. Not isolated.
		ICT-4 - For use on integrated circuits and other micro specimens. 0.013 " diameter 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 0.025 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 s. 5 ft. lead. Max. Temp. 150 °C. Other sizes made to special order. Not isolated.
		Ultra Fine IT-Series Flexible Microprobe IT-24P - Tiny, 24 gauge polyurethane coated wire with polyester insulated thermocouple bead. For research applications to measure temperature in animal brains and other tissue. Fairly fragile, but very fast responding. Wire cross selection 0.127 mm x 0.0635 mm (.005 " × .0025 "). Insulated tip maximum outside diameter 0.229 mm (.009 "). Length 91.5 cm (36 ") supplied on a protective spool as shown. Time constant .004 s. Maximum temperature 70 °C. Sterilization by Gas (ETO).

Time constant is defined as the time required to reach 63 % of final temperature in liquid. An accurate reading is obtained when the reading stops changing, typically 5-10 time constants.

Maximum Temperature refers to intermittent use of a probe. When probe is used for continuous measurements, max. temp. should be reduced by 25 % unless specified.
