Probe for Gemoro AGT1 and AGT3 electronic gold testers

Details Replacement pen-probe for Gemoro AGT1 and AGT3 electronic gold tester. We haven't sold the Gemoro testers for a few years but still get asked for these pen-probes occasionally, so we like to keep just one in stock. If you think your pen-probe will soon be used up, place your order now to avoid disappointment.   Warning. read this before buying: You MUST calibrate the tester when you plug in a new probe, so please make sure you have a sample of 14ct yellow gold (must be yellow gold, must be exactly 14ct). This is a 'consumable'. Consumables cannot usually be returned if unsuitable. When an AGT1 or AGT2 tester stops working, it might be because it needs a new probe but it might be because the machine has developed a fault. Maybe your tester does need a new probe...but it might also have developed a fault. Maybe your tester was working fine the last time you used it...but it might have developed a fault. Since we have no way of knowing if the tester is faulty or if it just needs a new probe (we discontinued this item several years ago) you may return a probe for refund providing it is posted back to us within three days of receipt. POSTAGE IS NOT REFUNDABLE. Please note, this product is for the AGT1 and AGT3 tester only, it will not work with any other model.
