The Aisko BACscan F-30 breathalyzer is a modern device designed for responsible drivers. A high-class electrochemical sensor offers a measuring range of 0.00-4.00 per mille with an accuracy of 0.05 per mille. The model is equipped with a digital display and memory for the last 10 measurements. The built-in thermometer ensures that the measurement takes place at the optimal temperature. Product features: possibility of calibration: yes (one calibration free of charge in the first 12 months of purchase) air flow sensor measurement counter measurement accuracy: 0.05 ‰ measuring range: 0.00-4.00 ‰ LCD display battery consumption indication additional features: automatic power off, electrochemical sensor, calibration reminder, memory for 10 measurements, 4 measuring units (possibility of changing the unit in the service) Accessories included: 2x AAA battery, 3x mouthpiece, warranty card warranty: 60 months To maintain the highest precision of measurement, the device should be calibrated once every 6-12 months or after 500 tests. BACscan F-30 is a high-class sobriety tester equipped with a modern, highly sensitive electrochemical sensor. The sensor offers a very good measurement precision, and thanks to its selective action it is resistant to other substances in the breath that could falsify the results of the sobriety test. The breathalyzer has a measuring range of 0.00-4.00 per mille and offers an accuracy of 0.05 per mille. The air flow sensor makes sure that the sample for analysis has been collected correctly. Thanks to its small dimensions and weight, the device can be comfortably carried with you and feel confident in any situation. The model is equipped with a memory of the last 10 measurements and a counter function to remind you of the calibration. A clear, two-color LCD display clearly shows the measurement results. The built-in thermometer ensures that the test is performed at the optimal temperature for the device, and thus is characterized by the highest accuracy. The big advantage of the BACscan F-30 model is its uncomplicated operation and trouble-free operation. The highest quality components were used for production, which guarantee reliability and durability. The advanced electrochemical sensor offers very good sensitivity and measurement accuracy. To maintain the highest precision of indications, the breathalyzer sensor must be calibrated (every 6-12 months or every 500 measurements).
