Introduction:
Thank you for purchasing our ACE AL5500 plus Breathalyzer.
It measures alcohol concentration in human breath using a
semiconductor sensor and calculates the blood alcohol level.
The device must only be used pursuant to the instructions
mentioned in this manual. In case of any questions you may
contact the distributor (ACE) by email to info@ace-instruments.

Note to country-specific measurement units:
Customers in the EU get the breathalyzer with ‰ (per mill) as
default setting, in the UK the default setting is mg/L and in the
USA it is % BAC. In the chapter “Technical data“ you will find in-
formation about the accuracy concerning the different measu-
rement units. Please check e.g. the website of the department
of transportation, the website of the Ministry of Transport or
of automotive clubs to get informed about the current alcohol
limits in your country.
Short description:
The ACE AL5500 plus Breathalyzer can be operated by only
one button. The test can be done in three different ways: By
means of using a mouth piece (= best accuracy), by means of
using a straw (= good accuracy) or by just blowing your breath
directly upon the sensor opening (= sufficient accuracy). The
test results have a tolerance of +/- 0.10‰ (per mill = default
setting) with reference to 0.50‰. For devices with UK mea-
surement unit the tolerance is +/- 0.05mg/L with reference to
0.25mg/L, for devices with US measurement unit the tolerance
is +/- 0.01% BAC with reference to 0.05% BAC. The test result
is shown on a display with 3 digits (2 decimals) and it can be
interpreted 1:1 - so if the shown test result is, e.g., 0.36 then this
means 0.36‰ = per mill (for UK: if the shown test result is, e.g.,
0.18, then this means 0.18mg/L, for USA: if the shown test result
is, e.g., 0.036, then this means 0.036% BAC).
The semiconductor sensor inside the ACE AL5500 plus
Breathalyzer can be calibrated. To maintain the measurement
accuracy of this breathalyzer it should be calibrated regularely.
For a calibration service you can send the device to ACE
Instruments (see www.ace-instruments.net).
For each breath test a new mouthpiece is recommended (for
hygienic reasons and also to avoid an influence on the test
results - a used mouthpiece may contain rest alocohol).
