E&C Division manufactures and sells high-resistance resistors and high-voltage measuring instruments.The range of resistance values cover a range from MΩ (mega-ohms) to TΩ (tera-ohms), and the product lineup includes everything from 1005-size chip resistors to power resistors with a DC voltage of 300kV (max), all of which are highly accurate, stable, and offer excellent long-term reliability.
We also accept orders for the production of various special products using our high-voltage, high-resistance manufacturing and measurement technologies.Our range of measuring instruments, which make the most of our position as a high-resistor manufacturer, includes precision resistor boxes that achieve a maximum resistance of 1P (1000T) Ω, high-voltage voltage dividers that can measure power supplies with low current capacity thanks to their ability to select input resistance up to 100GΩ, and digital high-voltage meters that can be controlled by a PC via GP-IB, etc.
We have a lineup of high-voltage measuring instruments that can be used in laboratories and on production lines.
