1507/1503
Insulation Testers
Technical Data
The Fluke 1507 and 1503 Insulation
Testers are compact, rugged, reliable,
and easy to use. With their multiple
test voltages, they are ideal for many
troubleshooting, commissioning, and
preventative maintenance applications.
Additional features, like the remote
probe on these tools save both time
and money when performing tests.
Features and benefits:

•
•
•
Insulation test range:
•
1507: 0.01 MΩ to 10 GΩ
•
1503: 0.1 MΩ to 2000 MΩ
Insulation test voltages:
•
1507: 50 V, 100 V, 250 V,
500 V, 1000 V
•
1503: 500 V, 1000 V
Save both time and money with
Automatic calculation of Polar-
ization Index and Dielectric
Absorption Ratio
Make repetitive tests simple and
easy with the 1507’s Compare
(Pass/Fail) function (only avail-
able on the 1507)
