Merck have introduced into the range of Titripur® Titrants some packs with additional technology - Supelco® SmartTitrants that use an RFID tag to provide a seamless data transfer between the smart titrator and the RFID tag on the label of the bottle of titrant. It will ensure that all information needed for method execution, result calculation and documentation is transferred to the titrator equipped with this technology. MettlerToledo Compact and Excellence titrators include this technology. Please see ordering table below for packs with RFID tag.
