The Alcometer® 400 is a breathalyser widely used by police forces all over the world for screening and evidential testing and is type approved by the Home Office(in its SL-400 configuration) in Great Britain, for use by UK police in the United Kingdom.
The operator turns on the device and connects a new mouthpiece to the sampling port. The individual is then instructed to blow through it until the sample is taken. A short time later, their alcohol level is displayed on the clear, easy-to-read display, which is illuminated for nighttime use.
After taking the reading, the operator removes and discards the mouthpiece. After a short delay, the instrument is ready to be used on the next subject as required. If necessary, the last test result can be recalled to the display. Each breath alcohol reading is also securely kept in memory, along with the date and time.
This instrument must be checked with an alcohol standard on a regular basis and, if necessary, recalibrated. The user can do this using an AlcoCal® product, or a service-by-mail. A Printer Kit [printer plus carry case] is also available for use with this instrument. This generates a permanent record of each test, with space for the manual of other details, such as names and locations. This may also be ordered as the complete 400P if required.
