Handy, fast and precise - three of the reasons that make the Alcotest 7410 (Plus RS) to become the world standard in hand-held breath-alcohol measuring instruments. The long-term stable DrägerSensor gives fast exact results on an illuminated display with three digits.

Features and Benefits of the Alcotest 7410 Plus RS:

• quick and long-term stable DrägerSensor: short waiting time until first test, quick determination of the measured value, quick retest rate and small standard deviation
• low blowing resistance
• real-time clock with date and time
• measurements are also possible without cooperation of the person being tested by passive sampling: triggered by pressing a button and afterwards qualitative detection of alcohol
• data memory for more than 9,700 measurement results with date and time information: the stored data may be recalled menu-driven by using a button on the instrument
• statistical options
• protocol print-out by the Alcotest 7410 Printer
• three different power supply units: with alkaline batteries (up to 600 measurements), with rechargeable accumulator (up to 300 measurements) or motor vehicle connection 12 V
• charging station with indication of charging condition and overcharging protection for accumulator power supply unit.
• a data interface (RS 232) for connection to a PC
• an input of person-specific data for a test and read-out of the up to 9,700 stored data sets with the Dräger PC Software “View 2000“
• evaluation, print-out and management of stored data.
