The ISOMETER® iso1065 is an insulation monitoring device designed primarily for use in oil and gas applications monitoring the degradation in subsea cables and umbilicals. The device is suitable for monitoring insulation resistance on unearthed IT systems.
The iso1065 Line Insulation Monitor (LIM) is a direct replacement device for the obsolete IRDH 1065, designed to provide a quick and easy upgrade that requires no additional equipment during installation.
There are two variants of the device, the iso1065 and the iso1065-M with analogue output.
The device has an LCD user interface to provide an accurate system overview and allow simple and intuitive parameterisation of all connected devices.
