You can change the sensor as fast and easy as replacing a battery. There is a small panel that opens exposing the sensor and in seconds you can replace your old sensor with a new Pre-Calibrated sensor module. Now your breathalyzer is like new again, there is no need to send this unit in for a calibration service. (see pictures at the bottom of the page).  

Since this proprietary sensor technology is patented there is no other brand of breathalyzer on the market that has this replaceable sensor technology. If you purchase a competitors brand you will have to mail your breathalyzer in for a calibration service and wait 4-6 weeks for it to return verses changing the sensor in a few seconds. 

Sensor life is between 200-300 tests and this unit also includes a sensor replacement indicator. This unit also has a test counter integrated into the memory and now features a 4 DIGIT LCD DISPLAY(0.000) for even more accurate alcohol testing!
