Test lab notes

De­sign: A sturdy, self-con­tained unit, the PT500 is bat­tery-pow­ered with a large bright orange LCD screen. The in­ter­face was sim­ple to use and the unit was fairly quick to op­er­ate once it was turned on.

Per­for­mance: We tested all three breath­a­lyz­ers against a stan­dard po­lice-is­sue In­toxime­ter Alco-sen­sor FST (re­tail price about $600) to pro­vide a base­line of per­for­mance. The PT500 tracked within range at lower lev­els of in­tox­i­ca­tion—it was dead-on at the .011 sam­ple and only low by .003 at the sec­ond sam­ple at .028. How­ever, that gap widened as our test sub­ject’s blood-al­co­hol level rose, and it was off by .005 at the third sam­ple and was low by .024 at the fourth sam­ple (taken at .087). This gap was un­ac­cept­able, and as a re­sult we can­not rec­om­mend this unit.

Price: $149.99. Man­u­fac­turer: Al­co­hawk
