Alcohol testers for checkpoint and patrol work
Checkpoint work asks three things of a tester that office screening does not: a reading that holds up over a long shift, a printed record with the date and time on it, and a way to screen a queue of drivers without a mouthpiece for every one. The instruments below are built around those three.

Every figure here is read from the product's own page. Where a product does not publish a number, this table says so rather than estimating it.
Which one
- A-23— Prints, and is the least expensive printing unit in the range.
- A19 Chita 1— Non-contact baton for screening a queue; no printer.
- A200— Fuel cell with a built-in thermal printer.
- A19 Chita 2— Non-contact baton that also prints.
- A15 Fingerprint— Ties each test to a fingerprint, so the record names the operator.
- A-9000— Fuel cell with a printer, at the top of the range.
Why a fuel cell sensor
A fuel cell responds to ethanol rather than to anything oxidisable, and holds its reading over a long shift. Five of the six instruments on this page use one; the A-23 uses a semiconductor sensor, which is why it is the least expensive of them and why it is recalibrated more often.
Why a printed record
A slip carrying the reading with the date and time, handed over at the moment of the test, is a record nobody has to transcribe. Five of the six print.
Why screen before you measure
A baton screens a queue without a mouthpiece for each driver; anyone it flags is then tested on a mouthpiece unit. That is the pairing most checkpoints end up with — a baton at the window and a printing unit in the vehicle.
Questions
- What is the difference between a baton and a mouthpiece tester?
- A baton screens without contact, so a queue can be checked quickly; a mouthpiece unit takes the measurement. They are used together — screen first, then measure anyone the baton flags.
- Which of these print a result?
- The A-23, A200, A19 Chita 2, A15 Fingerprint and A-9000 all print. The A19 Chita 1 does not.
- Can the record show which officer ran the test?
- The A15 Fingerprint ties each test to a fingerprint. The others do not identify the operator.
- Do you supply in bulk to departments and agencies?
- Yes. Send the quantity and the model and we will quote, including delivery.
