ZY9858 microhmmeter is an upgraded product for our unique Kelvin bridge, which is based on bridge circuit and select built-in precision standard resistor as reference. It not only possess the characteristic like multi-meter – simple, fast and striking, but also maintain the advantage of bridge circuit – accurate, stable and reliable. It is suitable for accurate measurement of DC low resistance in factories, universities, colleges, metrology center, laboratories, and worksites.
- Extremely wide range: from 0-2kΩ, 7 spans are available.
- Minimum resolution up to 0.1μΩ, especially suitable for accurate measurement of low resistance.
- Adopt 41/2 LED green large digit display, clear and legible.
- Main resistance element adopts manganin winding resistor, which characterized by small temperature coefficient, good stability and high accuracy.
- With RS232 interface for easy connection with computer.
