This Testing Gel Refill is for use with Tri Electronics Electronic Gold Testers models GXL-24 and GT-4000.
IGEM Instruments highly recommends that our customers use Expedited or Express shipping methods for Tri Electronics gold tester gel refills during times of extreme heat or cold weather. Exposure for extended periods to temperatures that are outside of the proper storage range (below freezing or above 85 F) might render the gels unusable. We are not responsible for damage caused by the customer's selection of a non-expedited shipping method. There will be no refunds or exchanges on testing gel refills.
