Notice Regarding Expiration of EN12830 Certification (TR-51i/52i, RTR-501/502)

The TR-51i/52i and RTR-501/502 have been introduced as data loggers compliant with the European standard EN12830. However, as a result of our review, we have confirmed that the EN12830 certification has already expired. Therefore, references to EN12830 compliance will be removed from the product pages on our website and catalogs.

Please note that this change does not affect the products’ specifications, such as waterproof performance, durability, or measurement capabilities.
