ZTWS-8A moisture analyzer

ZTWS-8A moisture analyzer

Designed using the principle of Karl Fischer Coulomb method (electric quantity method), with blue screen LCD display, fully Chinese interactive menu, user-friendly human-machine interface, and built-in calculation formula of the instrument, it can directly display the moisture content percentage of the sample; The detection circuit adopts digital processing, which overcomes the large temperature drift, testing accuracy and sensitivity of traditional measuring instruments. The whole machine adopts a relay free process design, which reduces the service life of the instrument due to the oxidation of memory relay contacts. Equipped with a printer interface, users can choose a micro printer according to their needs for data retention. It has been applied in departments such as power, petroleum, and chemical, and is one of the cost-effective products launched by our company.
