Best breathalyser-alcofind-da-7100

This certified breathalyser offers a wide measurement range - up to 5 ‰ and repeatability of results (0.05 ‰). Measurement results can be also displayed in mg/l. The DA-7100 construction is based on the highly efficient electrochemical sensor so that the readings are much more reliable than in conventional semiconductor systems. A high quality sensor offers great stability and durability. A calibration is required after up to 500 measurements (but not less frequently than once a year). In addition, the breathalyser has a built-in counter of measurements and monitors sensor status before each measurement (which prevents doing the test if sensor is not completely cleared of alcohol vapours left over from the previous measurements). Using the breathalyser is facilitated by sound notification of readiness to measure, an auto power off function and a low battery indication system.

The DA- 7100 breathalyser is the best solution for both home users and companies. It offers a high-performance electrochemical sensor, wide measuring range, high precision, repeatability and user-friendlinessy. It is certified and quality tested.

Advantages of AlcoFind DA-7100

  • Pre-recording


    An electronic counter keeps track of how many measurements have been performed, and will remind you when the next calibration is due.

  • Recording activation


    Proper operation is checked by a built-in status-monitoring sensor , so that you do not have to worry about the state of the breathalyser.

  • Recording schedule


    The breathalyser uses advanced electronic components, allowing it to provide results with an accuracy of 0.05% , which is comparable to the results of breathalysers used by the police. The breathalyser selectively measures alcohol molecules and avoids incorrect measurements so it can obtain true results.

  • Sounds


    An audible buzzer makes carrying out the alcohol test easier. The sounds indicate readiness to measure. They tell you when to stop exhaling, and they also warn when the battery is low.

  • Long battery life


    An energy-saving design allows you to perform up to 1000 tests on a single set of batteries.

Service and warranty
