The CA 9000 Professional SG breathalyzer is a high-quality breath alcohol tester equipped with a sensitive electrochemical sensor for accurate measurement results. It features an air flow sensor, measurement memory, and measurement accuracy of ±0.01 ‰ with a range from 0.00 to 4.00 per mille. The device includes an LCD display with backlight and an alarm. The analyzer has a control system that checks proper operation before and after each measurement. A high-quality electrochemical sensor displays results on a backlit, two-color LCD screen with resolution up to two decimal places. The built-in temperature control module prevents measurements if the operating temperature range is exceeded, protecting the device and ensuring accuracy. The unit includes a counter for total measurements and stores the last ten results in memory. Calibration is recommended every six to twelve months or after 500 measurements, whichever occurs first.
