Product Description

Made in China High Quality ZX90E-ZX99E Decade Resistance Box

I.Introduction
 

1. Introduction

Type ZX90E~ZX99E DC resistor is a multiple - valued resistor, formed by decade resistor groups in series. The resistance between both fasteners can be changed with the position of the switch brush contact.

The resistor is miniature and portable. The switches are fully enclosed, no .need to clean, low pressure of contact , long life time and less variations. The stand of the resistor is made of plastic so that the insulation resistance is high. The readings of resistance on the panel is lined up, and can be read forthright and clearly. The resistance elements are all wound noninductively with enameled manganin wire, and go through strict technical process, in this way, the resistor has high stability and can be used in any position.

 

2. Applications

2.1. It is suitable for electric measurement and other experiments in factories, schools and scientific research units.

2.2. It is used as adjustable precision resistor in DC circuit.

2.3. It is even more suitable for calebration of resistance thermometer.
