The Bio-Thesiometer Diagnostic Apparatus (VPT- I) is an easy-to-use and non-invasive diagnosis of neuropathy. It is consist of the host apparatus and the vibration probe, which could provide local vibration, and with the patient’s reaction to the induction, to auxiliary diagnose the neural induction system diseases.

This apparatus designed to measure the threshold of appreciation of vibration in human subjects simply and accurately.

Voltage: AC 220V 50HZ                             Security type: Ⅱ-B.

Input Power:30W                                       Ambient temperature: 0-40°C 

Relative humidity:≤ 80%                            Fuse model:220V 1A

The BioThesiometer is used to test the body surface neuropathy vibration perception thresholds,early diagnosis of the diabetics hypoesthesia,peripheral neuropathy perception threshold testing,high-risk foot disease testing,sexual dysfunction diagnosis, deep perception nerve fiber testing.

1.VPT+ 2. VPT - 3,record 4,start/stop

1) VPT+: Press the button to increase vibration intensity by 1 during the test. The vibration peak is 50 VPT, and the boot default is 0 VPT

2) VPT-: Press the button to decrease vibration intensity by 1 during the test. The lowest vibration is 0 VPT.

3) Record: Press the button to send current threshold data to computer.

4) Start/Stop: Start or stop vibration output
