The AL 9000 Lite is one of the most advanced breathalysers in its class. It is designed for customers who value the appearance and accuracy of their measurements combined with ease of use.The breathalyser housing is made of aluminium alloy and high quality plastic. The tester is therefore more resistant to damage. Thanks to the black colour and silver-plated inserts and inscriptions, the tester looks impressive. The alcohol tester is very lightweight, so it is not a burden on your pocket or purse.The use of an electrochemical sensor similar to the one used in police testers makes the result very accurate. The wide measuring range up to 4.00 parts per thousand allows you to measure the level of alcohol in the exhaled air even after a large amount of alcohol.The AL 9000 Lite is one of the easiest breathalysers to use. All operations are carried out with a single button on the front of the breathalyser, just below the display.The measurement consists of switching the device on and when the BLOW message appears on the tester LCD display, start blowing air through the mouthpiece (about 5 seconds) into the breathalyser. The audible alarm will tell you when the test starts and ends, so you don't have to look at the display during the test.The time between each test is about 5 seconds to 5 minutes (for very high alcohol concentrations), so you can safely do another test immediately after the previous one. It works great if you plan to take readings at very short intervals for a large number of people.The AL 9000 Lite alcohol meter operates in temperatures between 0 and 40°C, so changing weather conditions will not affect the proper operation of the alcohol meter or the accuracy of the readings.The low battery indicator ensures that you will always know when to replace the battery.The AL-9000L can check the number of readings taken so you know exactly when to calibrate. The meter counter is displayed by pressing and holding the switch button for a few seconds while the tester is started.TECHNICAL SPECIFICATIONSPage informationNo free calibrationMeasuring accuracy [‰] up to 0,01Calibration possible YesTemperature range [°C] 5 to 40Sensor type electrochemicalMeasuring range [‰] 0-4Power AAA x 2Further informationThe device has automatic power offMeasuring time [s] up to 5Preparation time for work [] up to 5 Components of the breathing setAAA batteries x 2 pcs. ,case,case,nozzles × 5 pcs,instructionsDominant colour blackAdditional colour whiteBattery charge indicator YesLCD display isDimensionsThickness [mm] twentyWeight [g] 100Total width [mm] 50Total height [mm] 106WarrantyWarranty period 24 months
