Pre-shift alcohol testing on a construction site
Pre-shift testing is a throughput problem: every worker, at one gate, in the few minutes before a shift starts. A non-contact unit does that without a mouthpiece for each worker, with one printing unit kept aside for anyone it flags.
4 models, 
4,000 to 20,000, excluding tax. Full price list
| Model | Sensor | Detection range | Response | Price (excl. tax) |
|---|---|---|---|---|
| AX5 | Non-Contact Sensor | 0.00–0.19% BAC (0–1.9 g/L) | Less Than 5 Seconds | 4,000 |
| A-18 Rapid | Non-Contact Sensor | 0–400 mg/100mL BAC | Less Than 5 Seconds | 10,000 |
| A15 Blue | Semiconductor Sensor | 0.00–0.19% BAC (0–1.9 g/L) | Less Than 5 Seconds | 11,000 |
| AT-7000 | Non-Contact Sensor | 0–2.000 mg/L (Equivalent to 0–440 mg/100mL BAC) | Less Than 1 Second | 20,000 |
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
- AX5— The least expensive non-contact unit; one gate, one device.
- A-18 Rapid— Reads to 400 mg/100mL, the widest range of the semiconductor units here.
- A15 Blue— A step up from the AX5 for a busier gate.
- AT-7000— Fuel cell, reading in under a second.
Sizing it to the crew
A small crew at a single gate is served by the AX5. Two gates or a shift change is where the A-18 Rapid and A15 Blue earn their price, and the Rapid reads to 400 mg/100mL. Where readings are written into a register, the AT-7000 is the one to buy: a fuel cell sensor drifts less than a semiconductor one between recalibrations.
Keep a record for the exceptions
None of the units on this page print. An A-23 alongside them does, and that is the usual pairing — screen everybody at the gate, print a record only for the workers the screen flags.
Questions
- How long does testing a crew take?
- The non-contact units here read in under five seconds and the AT-7000 in under one, after a short warm-up. The gate, not the device, is usually what sets the pace.
- Why is the AT-7000 several times the price of the AX5?
- The sensor. A fuel cell drifts less than a semiconductor sensor over repeated tests. Both are recalibrated; the semiconductor units need it sooner.
- Does a non-contact unit need a mouthpiece for each worker?
- No, which is the reason to use one at a gate.
- Which of these print a result?
- None of them. The A-23 prints and is the usual unit kept alongside for anyone the screen flags.
- Can you supply several sites?
- Yes. Send the number of gates and we will quote.
