Product brief
The YTD221 volume resistivity tester meets the requirements of the DL421-2009 new volume resistivity measurement standard and is a high-end fully automatic single cup volume resistivity tester with functions such as automatic oil pumping, automatic oil drainage, automatic testing, and automatic cleaning. The YTD221 model adopts numerous advanced technologies and processes, such as the unique DC high-voltage power soft loading technology, which fundamentally overcomes the inherent strong interference problem of high-voltage power supply connection and has strong anti-interference ability. YTD221 adopts a 24 bit high-precision AD converter, which has high accuracy and good measurement repeatability. The design of YTD221 emphasizes the value of customer experience, with novel appearance design, exquisite structure, sensitive and comfortable operation, etc. It is an updated product of existing products in the market and can be widely used in fields such as electricity, petroleum, and chemical industry.
