The device is effective when used as part of an electrical laboratory.
Functional features of REIS-405:
- The device is made in the form of a monoblock and combines the capabilities of 4 measuring instruments, including a reflectometer for metal cable and overhead lines, an insulation resistance meter, a meter using the pulse-arc method and a meter using the oscillatory discharge method.
- The device is equipped with a wide color display. You can also connect an external display of any size to the device for ease of control.
- A powerful probing signal and an increased measurement range expand the possibilities of using the device.
- Convenience of testing is ensured by a simple and intuitive interface of the device and direct control of measurement parameters.
- Compact size, light weight and convenient location of controls and connections
- Suitable for stand-alone use and as part of electrical measuring laboratories for detecting, identifying and determining the distance to defects in power cable lines and other types of lines with metal conductors.
