The TestBoy TV455 is a portable insulation resistance (Riso) measuring device.

The Riso TestBoy TV455 portable insulation resistance tester is used to carry out:

• insulation resistance measurement  at 1000 V, in accordance with the IEC61215 standard in order to identify and document problems in insulation resistance (Riso) in PV modules/parks
• insulation resistance measurement in wet conditions at 1000 V, in accordance with IEC61215 standard par.10.15, in order to identify and document defects in insulation resistance (Riso) in PV modules. The test is performed at our headquarters at the same time as the full laboratory test carried out with the Mobile PV Testcenter.
