CE Compliance

Onset products have been CE compliant for many years. Recently the European Union changed the CE regulations, effective July 20, forcing Onset to either change the circuitry in some products, or choose to no longer list them as CE compliant. In most cases we offer CE compliant alternative products.

Rest assured Onset has placed a high priority on making all current products CE compliant before year-end. If you are not shipping this item to a EU country after July 20, please disregard this message.

This product is not CE compliant. If you are shipping to a EU country, Onset recommends using CE compliant part # U12-013
