The NTE-3 Thermal Probe is a sophisticated, non-invasive device for the clinical evaluation of neuropathy and the assessment of short fiber neurological function. Individual thresholds are compared to normals to statistical normals. These results provide an accurate means of tracking chronic changes in small fiber nerve function. It can be used for pain studies and in any application where a variable, accurately-controlled temperature stimulus is required. The NTE-3 is often used in conjunction with the Vibratron II to assess peripheral neuropathies.

The equipment comprises a handheld pen-shaped probe (Thermode) with a smooth flat tip 13mm in diameter on a 5 foot lead, a digitally set PID temperature control unit provided with a software package which permits the administrator to generate thermal ramps and log thermal pain thresholds temperatures automatically too a .csv file as well as export date as an Excel spreadsheet with time/date stamp.

The thermal probe, or thermode, is driven by a thermoelectric (Peltier effect) module. These modules have the unique ability to provide a controlled temperature with feedback sensor to stimulus above and below room temperature in the physiological range. The temperature range of the thermode extends from 0 to 60°C and the response time to a step change in temperature is extremely fast, less than 4 seconds in the heating or cooling mode.

The thermoelectric module requires a trickle of water through the thermode heatsink to extract the dissipated heat. This is done with the supplied HE-1 Heat Exchanger, closed loop water circulator pump.

The equipment can be supplied for 110-120V or 200-240V AC operation. Please specify when ordering.
