HUMAN BODY STATIC DISSIPATER

Human Body Static Dissipator

To discharge the static charge developed in human body to the ground, human body static dissipator provides

complete solution, by measuring the resistance of human body and providing conductive path for static charge

dissipation to earth. It ensures that, the human body resistance is below 1000K Ohms and safe from risk of

spark generated due to static discharge, prior to entering into hazardous area.

Operation Principle

Human body static dissipator measures the resistance of human body and displays ‘Pass or Open’ depending

on the measured value of resistance. It also provides path for static charge of the human body to discharge to

earth. When human body has static charge, the resistance is typically above 1 Mega Ohm. When the human

body is discharged the resistance falls below 1 Mega Ohm. When the resistance is above 1 Mega Ohm, the

device displays ‘Open’. When the resistance is below 1 Mega ohm, the device displays ‘Pass’. A relay output

contact is available which can be used for annunciation or interlock with the access door or gate to restrict

entry of people only after static charge dissipation.
