Biothesiometer for Peripheral neuropathy

Biothesiometer is a simple tool used for managing the peripheral neuropathy and diabetic neuropathy due to loss of vibration perception threshold (VPT). Biothesiometry Study helps to prevent diabetic foot ulcers. For more details visit www.digitalbiothesiometer.com.

1. Digital Biothesiometer
Vibrometer
◼Electronic Tuning Fork
◼Tool to Quantify
◼Vibration output in Voltage format
◼0 to 50 Voltage variable vibration output
◼Voltages are internationally accepted
◼Usually vibration output units are micron
but not used as an indicator

2. Feature contd..
◼Check key to confirm reading
◼Computer connection thorough USB cable
◼Windows based computer supports
◼Data transfer to Computer
◼Works in 200 ~ 230 Volts supply
