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.
The new RET-3-ISO for mice and neonatal rats has all the same features of the RET-3 plus:
* an isolated sensor (can be used with montoring equipment where electrical interference from other electrodes may be present).
* Reinforced strain relief for applications where probe is in more frequent use.
* Smooth ball tip. Stainless steel – 3/4” long, .028” dia. Tip diameter .065”. 5 foot lead length. Time constant 0.5 secs.
The new RET-4 Rectal probe for very small animals (neonatal mice). Flexible polyurethane sheath with smooth rounded tip (see inset). 36” long (can be made longer). Outside diameter nominal 0.032” (max at tip 0.04”). Time constant 0.18 seconds. Max temp. 140°C. May be sterilized by Gas (ETO), Gluteraldehyde solution or autoclave.
Teflon sheathed thermocouple wires are implanted with regular hypodermic needle. 14ga. or 17ga.
When ordering, specify: Probe series (IT), needle gauge, number sensors and distance between sensors.
(e.g.: IT-17(3) is implanted with 17 ga needle and has 3 sensors. Unless otherwise specified we put sensors 1cm apart, starting at tip.)
These stainless steel microprobes have closed, sharpened tips. We can put up to 3 sensors in a 23ga needle and 1 or 2 sensors in a 26ga needle.
MT Series Needle Microprobes
When ordering, specify: Probe series (MT), needle gauge, needle length, number of sensors and distance between sensors in cm.
e.g. MT-23/5(2) is a 23ga needle, 5 cm needle, 5cm long with 2sensors. Unlessotherwisespecified sensorswill be lcm apart, starting at tip.
We also manufacture interchangeable single sensor probes and microprobes available in many configurations. Our thermocouple probes include clinical probes-skin, rectal, oral and esophageal. There are implantable needle and flexible sensors and probes for measuring surfaces, liquid and air. See our data sheet on interchangeable probes and sensors for more descriptive information on individual probes.
