Needle Microprobes

Needle Microprobes

Fast-response needle temperature probes for instant readings in tissue, semi-solids,  liquids. Suitable for very small specimens, powders and materials. Needle tip  is sealed to ensure only stainless steel contacts specimen. Max. Temperature 200°C. 5ft. lead.


Features

  • Fast time constant
  • Non isolated
  • 200°C Max. Temperature
  • 5 ft lead length
  • Withstand sterilization by ETO gas or gluteraldehyde

Options

Smallest microprobes will give the fastest readings. Shorter length needle microprobes are easier to insert and will last longer

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 intermit tent use of a probe. When probe is used for continuous measurements, maximum temperature should bereduced by 25%.

Applications

Fast-response needle probes for instant readings in tissue, semisolids, liquids, very small specimens, powders and materials. Needle tip is sealed to ensure only stainless steel contacts specimen.

Probe Sterilization Methods

The needle microprobes and animal rectal probes are all designed to withstand sterilization by ETO gas and gluteraldehyde solution.
