SpectraPure®'s Magnetic Probe Holders were designed for professionals and hobbyists alike! These are the strongest holding aquarium/sump probe trays on the market. Designed using the most powerful magnets available, fully encapsulated and with contact/mounting surfaces backed using a high-tech polymer material that will not slip on wet aquarium walls, these holders securely hold their position on tank walls up to 3/4 inch (19mm) thick. The 2 position model has probe holes and set screws for 2 probes or sensors; one 0.5 inch (12.7mm) diameter probe hole on the right and one 0.68 inch (17.3mm) diameter probe hole on the left. Both probe holes are equipped with large nylon thumb screws for securing probes or sensor tubes vertically as desired. Rubber bushings can be used to better accomodate smaller diameter probes or sensors, making these trays compatable with most probes on the market. Problems with slipping suction cups or weak magnetic holders are now a thing of the past!
