Researcher, Imperial College National Heart and Lung Institute

Julian was fantastic, he patiently walked me through the steps for diagnosing issues with our syringe pump. We found it was a simple belt that was broken and he sent out a replacement part the same day.

Needle Microprobes (Type T Thermocouple)

Needle Microprobes (Type T Thermocouple)

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. Type T thermocouple.


Features

  • Type T thermocouple
  • Fast time constant
  • Non isolated
  • Temperature range -50°C to 200°C
  • ± 0.1°C accuracy over physiological range
  • 5 ft lead length
  • Blunt tip options for surface temperature measurements (MT-4, MT-D)
  • Suitable for sterilization by autoclave, ETO gas, Gluteraldehyde or Isoprophyl Alcohol

Options

  • 23ga needle diameter 0.025" (0.63mm)
  • 26ga needle diameter 0.018" (0.46mm)
  • 29ga needle diameter 0.013" (0.33mm)
  • MT-D drawing

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.
