Introduction
The lion alcolmeter® 900 devices are hand-held portable instruments for
fast, on the spot determination of a subject’s breath (or blood) alcohol
concentration level. They are some of the latest in the range of lion
alcolmeter® instruments produced by Lion Laboratories Limited of Barry,
South Wales, in the United Kingdom. Lion Laboratories is a company
specialised in breath alcohol detection technology for applications in
traffic law enforcement, commercial health and safety, and in medicine.
This handbook explains the following aspects of the instrument, so please
read it carefully:
•Basic principles of operation.
•How to run a breath test.
•Interpretation of results.
•Care and basic maintenance.
•Calibration checking.
•Calibration adjustment.
•System configuration.
Principle of Operation
The lion alcolmeter®900 uses an electrochemical fuel cell sensor to
measure the concentration of alcohol vapour in the subject’s expired
breath, a measured amount of which is drawn from the mouthpiece into
the fuel cell by means of the sampling system.
In the fuel cell a voltage is generated in proportion to the breath alcohol
concentration: it is amplified and displayed in terms of the subject’s
alcohol level.

The breath sampling system is factory-set to sample deep-lung air; it is the
breath from the bottom of the lungs that truly reflects the amount of
alcohol in the body.
To ensure repeatable and accurate results across the temperature range,
and particularly at low temperatures the lion alcolmeter®900 uses a
heater to heat the metal sampling port and the inlet port of the fuel cell.
This stops the build up of condensation which can affect the alcohol
concentration in the sample.
