Police Alcohol Tester (South Korea) Model:ZPW908CA2000

Police Alcohol Tester (South Korea) Model:ZPW908CA2000 Item: ZPW908CA2000 Alcohol Tester is a highly reliable, high-precision, breath-alcohol detector. ZPW908CA2000 Alcohol Tester core component of using new high-tech micro-variable-oxide semiconductor, can accurately detect alcohol content of gas, and not smoke, cola, coffee and other non-alcoholic gases interference. ZPW908CA2000 Alcohol Tester lightweight, simple operation, is the best choice for portable applications. 1, ZPW908CA2000 Alcohol Tester Profile ZPW908CA2000 Alcohol Tester is a highly reliable, high-precision, breath-alcohol detector. Its core components using new high-tech micro-variable-oxide semiconductor, can accurately detect alcohol content of gas, and not smoke, cola, coffee and other non-alcoholic gases interference. ZPW908CA2000 small and lightweight, simple operation, is the best choice for portable applications. 2, ZPW908CA2000 Alcohol Detector Detection Principle ZPW908CA2000 Alcohol Tester with N-type conductivity when the oxide when exposed to the atmosphere will be reduced due to oxygen adsorption quantity of its internal e-its resistance increases. If the atmosphere there was a specific reduction of gas, it will respond with the adsorbed oxygen, thereby increasing the number of electrons within the oxide, resulting in reduced oxide resistance. ZPW908CA2000 Alcohol Detector semiconductor - oxide sensor is through changes in the resistance to analyze the gas concentration. 3, ZPW908CA2000 Alcohol Tester Technical Specifications and Features ZPW908CA2000 Alcohol Detector Sensor: Highly selective semiconductor - oxide alcohol sensor 3 Digital Display (x.xx% BAC / BRAC) Detection range: 0.00 ~ 0.40% BAC or 0.00 ~ 4.00mg / l Detection Accuracy: ± 0.01% (0.01BAC) or ± 0.05mg/liter (0.50 BRAC) Recovery Time: 30 seconds Preheating time: 20 seconds Induction time: 5 seconds Very low power consumption: a 9-volt battery can detect 300 square more times. Character bright: red LED display data, clearly visible at night. Sound Alarm: alcohol content overrun when the automatic alarm buzzer. Calibration: BAC simulator. 4, ZPW908CA2000 How Alcohol Tester 1, press the power switch, apparatus for internal self-inspection and preheat to show the countdown from 200 to 0 and lasted 20 seconds. 2, timing the end of a voice prompt, while green glow, while the middle of the yellow light flashes, indicating a normal instrument, you can begin testing. 3, tube alignment blowing into the holes 4 seconds, if alcohol is detected, buzzer alarm, red, green light flashes at the same time. In another 4 seconds, showing the concentration of data, if the concentration of between 0.00 and 0.40, only the green light flashes; if greater than or equal 0.50, only the red light flashes, accompanied by rapid voice of alarm. Concentration data for 15 seconds after the instrument display becomes OFF. (Note: Due to the display mode is extremely sensitive, so if the equipment inside a little bit of residual alcohol, gases, there will be a small digital display) 4, from blowing or alcohol was not detected within 30 seconds after boot without any testing, instrument display from 000 becomes OFF. 5, when the instrument display OFF, the need to re-start the measurement. 5, ZPW908CA2000 Alcohol Tester Notes 1) the prohibition to blow smoke inside the pores; pores can not enter inside the liquid; Do not block out the vent. 2) The yellow light indicated that the supply voltage is low, in need of replacement batteries.
