1555/1550C
Insulation Resistance Testers
The 1555 and redesigned Fluke 1550C
insulation resistance testers offer digital
insulation testing up to 10kV, making
them ideal for testing a wide range
of high voltage equipment including
switchgear, motors, generators and
cables. Fluke insulation testers can now
conduct the entire range of test voltages
specified in IEEE 43-2000 with a best
in class, 3-year warranty and CAT IV
600 V safety rating. With measurement
storage and PC interface, the 1555 and
1550C are perfect tools for preventative
or predictive maintenance programs
designed to identify potential equipment
failures before they occur.
• Test voltages up to 10 kV (1555)
provides solutions for all applications
• CAT III 1000 V, CAT IV 600 V safety rating
• Voltage breakdown detection alerts the
user that voltage is present and gives
the voltage reading up to 600 V AC or
DC for increased user safety
