Under Your Skin
We are made up of hundreds of organic chemical compounds that are naturally present in all of us. Alcohol isn’t one of them. Using infrared light the TT2500 detects alcohol out of all of the other chemicals that make up the skin of the person touching the sensor and measures the exact amount of the alcohol that isn’t supposed to be there.
The TruTouch touch test is fast and accurate. Re-calibration is automatic.
The relative proportions of naturally occurring compounds that make up skin is unique to every individual. The TT25000 can detect one person out of thousands based on a biometric template. The odds of beating the biometric test are low enough to deter attempts to do so.
