IITC Electronic von Frey

The IITC Life Science the original Electronic von Frey Aestehsiometeris used to assess mechanical allodynia with rigid tips (threshold) and the “Supertips™” (flexible von Frey hairs) are used for sensory test on all test subjects from all animal test subjects and human studies.

The 2390 series enables researchers to use up to 5 total test disciplines wath a single unit. Multiple users have the ability to use one single unit for multiple studies.

The IITC Life Science the original Electronic von Frey Aestehsiometeris used to assess mechanical allodynia with rigid tips (threshold) and the “Supertips™” (flexible von Frey hairs) are used for sensory test on all test subjects from all animal test subjects and human studies.

The 2390 series enables researchers to use up to 5 total test disciplines wath a single unit. Multiple users have the ability to use one single unit for multiple studies.


The systems are supplied with either a 90, 800 or 1000 gram probe. Probe type is determined by test subject.

When studies call for pain threshold, rigid tips are used when measuring sensory threshold one of the 15 Supertips™ are used. The IITC hairs are unique in design - each hair has a uniform tip of .8mm in diameter, eliminating the possibility of false readings that may occur due to the varying hair thickness when applied to test subject.

The systems will allow you to measure, store and display your test readings in grams based upon the amount of pressure applied. Manually calculating results is no longer required with the IITC system.

Testing is simple, choose one of the supplied tips place on probe tip; apply pressure probe to test subject, upon reaction the unit will display and store your reading in grams, an easy, quick test system for all pain studies.

An internal load cell is attached to the small tip, this is the central element in the system; which connected to the electronic system allows you digitally record your test results.

All EVF systems are calibrated at the factory and do not require any type of constant calibration, adjustment or separate calibrator to be purchased.

The optional analog output cable supplies a pressure analog output voltage (mV range) exactly proportional to the applied pressure. The signal is free floating and can be used on both chart recorders and/or AD converters.

Our system is an easy, user friendly system which was developed to replace the traditional hairs but at the same time enabling researchers to not only test sensory but pain threshold in one system.

What are “Supertips™”

As reported by earlier papers varying probe diameter on von Frey hairs is a serious problem. These patented “Supertips™” have a UNIFORM TIP DIAMETER OF .8mm ON ALL 15 DIFFERENT VON FREY HAIRS! This is a unique feature available only on Electronic von Freys by IITC Inc. Probe size no longer affects pain or pressure thresholds and results are finally comparable! All tips can be ordered individually.
