Non-contact Alcohol Detector / Alcohol Checker 3R SYSTEMS 3R-ALCH01, 2 units Used 397 times, 152 times. Purchase date unknown. Plus one more unit, usage count and purchase date unknown. This is a set of 3 used units for sale. The 3R checker displays the number of uses, but the other unit does not have this feature, so it's unknown. Judging from the condition of the outer box, I don't think it has been used much. The purchase date is unknown, so the one-year replacement guideline may have passed. Shipping costs are included in the bid price, so there is no additional burden. Please bid for all three units together. The color may not be accurately reproduced due to the lighting. At first glance, there appear to be no problems that would hinder use, but there may be defects that I have not noticed. Please judge the condition from the images, and no claims or returns are accepted. Cancellations and returns due to the bidder's circumstances are not accepted under any circumstances, so please consider carefully before bidding. 3R Alcohol Checker 3R-ALCH01 Brand: 3R
