Petroleum Product Karl Fischer Moisture Analyzer MKV-710M/MKV-710S/MKV-710B
principle
Weigh a certain amount of sample and inject it into the titration container of the Karl Fischer potentiometric titrator containing the titration solvent. Titrate the water content with Karl Fischer reagent until the potential endpoint.

The main features of the Karl Fischer moisture analyzer MKV-710M/MKV-710S/MKV-710B for petroleum products are:
MKV-710M: Wireless connection between touch screen and operation unit, while controlling four automatic titration measurement units.
By using a wireless adapter (Bluetooth), the operating unit and titration device can be connected without cables. When there are harmful gases during the measurement of the sample, the titration device can be placed in the smoke exhaust cabinet and the titration can be performed by the wireless transmission operation unit.
MKV-710M/MKV-710S/MKV-710B: Special switch valve for burette unit. Reduce dead volume between burette and switch valve. The design of special structures can reduce the amount of titrant used and quickly replace titration units.
