K90365 Coulometric Karl Fischer Titrator
The K90365 offers new standards in versatility and ease of operation. Providing fast, accurate and reproducible determinations of water content in liquids, gases and powders. This easy to use titrator incorporates many state-of-the-art features. Designed to be equally suitable for meeting the routine needs of the Quality Control laboratory or the more demanding and varied requirements of research applications. Hard copies of results are provided by the built in high-speed thermal printer, along with statistics, data input parameters, sample ID numbers and time/date of analysis. At the heart of the K90365 is state of the art ACE (Automatically Compensated Errors) control system. The ACE control system guarantees that the actual electrolysis current produced and the count rate displayed are always correctly synchronised, regardless of changes to the electrolysis cell resistance.
