The Lion Alcolmeter 500, available from Variohm Eurosensor, is a breath alcohol measuring instrument designed for field use by public services and other authorities for fast subject screening.
This screening is intended to ensure safe alcohol levels, in many instances before a vehicle or dangerous machinery is actually operated.
The Lion Alcolmeter 500 is a breath alcohol measuring instrument designed for field use
The Home Office-approved instrument complies with the accuracy and reliability standards for such equipment and uses high-reliability temperature sensors from Betatherm, supplied by Variohm Eurosensor, its exclusive UK distribution partner.
Temperature sensors used in breath alcohol instruments are essential to maintain that the subject breath temperature falls within an acceptable range and to provide the means to compensate for minute breath temperature variance for the test result.
Along with other measured criteria, breath temperature levels help to determine the validity of the breath sample; if, for any reason, the temperature is out of its normal and relatively narrow range, the Alcolmeter 500 will register an alarm.
To maintain such a high specification, the Alcolmeter 500 uses ultra-small bead thermistors from Betatherm.
These sensors utilise metallic oxide semiconductor material sintered on platinum/iridium alloy lead wires with a controlled glass coating that provides a hermetic seal.
With fast response times and high-power sensitivities, the technology is suitable for gas flow or liquid temperature measurement and their small size (0.25mm in diameter) makes them ideal for portable instruments.
Other applications for this temperature sensor are gas chromatography and thermal conductivity gas analysis equipment.
The Betatherm range of thermistors is used in demanding temperature measurement, control and compensation applications in biomedical, automotive, aerospace, instrumentation, heating, ventilation and air conditioning (HVAC), consumer industries and instrumentation.
