HM401 Automatic Transformer Moisture Test Equipment

Oil Micro Moisture Tester,
Fully Automatic Micro Moisture Tester,
Karl Fischer Moisture Tester.

Product Description


Karl Fischer Coulomb titration is the most reliable method to detect trace moisture for different substances, which was utilized successfully by DH401 trace moisture titrator. What's important, this instrument is able to work more reliably and conveniently by using the most advanced control circuit and 32 bit embedded microcontroller processor as the master control core and utilizing embedded mini operating system. Character with fast analyzing speed, simple operation, high precision and strong automatism, the trace moisture titrator has been widely used in the industry of petroleum, chemical, power, railway, pesticide, medicine and environmental protection.
