29 Gauge Surface Needle Microprobe with right angle bend

Fast-response 29 gauge needle surface probe for locating inflammation, arteries, etc. Also for dental use. 1/4'' right angle needle length, 3/4'' needle distance from lead. 5.5'' long handle for ease of use. Needle tip is sealed to ensure only stainless steel contacts specimen. Max. temp. 200°C. 5 ft. lead. Sensor within .3mm of tip. 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-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.

All needle probes are non-isolated. Isolated versions of 23 ga. and larger needles are available for special order.

Autoclavable version of any needle probe can be made as a custom order. Please call to request HT autoclavable version.

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 probe. When probe is used for continuous measurements, maximum temperature should be reduced by 25% unless specified.
