New electrochemical sensor technology delivers accurate and reliable results. The high stability and accuracy provided by this sensor technology make it suitable for use in traffic control and medical services. In the NAM-07's automatic measurement mode, measurements can be taken on people capable of sufficiently blowing into a tube. Manual and passive measurement modes also allow for measurements on patients and unconscious people who are unable to sufficiently blow into a tube. Three buttons ensure ease of use. Furthermore, the device is completely user-friendly, with a choice of languages according to countries, user guidance using on-screen button symbols, and warning and error messages expressed in sentences. Its high-capacity memory allows for long-term data storage. Using the NAM-07's buttons, you can search through all data in memory using various criteria. The retrieved data can be displayed on the screen, and a report from the archived records can be generated, if desired, via an optional printer. Data in memory can be transferred to a PC for archiving purposes, if necessary. Measurement results can be displayed along with other information using an optional thermal printer or dot matrix printer. The thermal printer's integrated keyboard provides additional data entry functionality. Using an optional external keyboard or the keyboard integrated into the thermal printer, it's possible to record additional data into the breathalyzer, such as first and last name, ID number, service ID number, etc.
