Fluke 1555 and 1550C Insulation Resistance Testers

Fluke 1555 and 1550C Insulation Resistance Testers
Fluke 1660 Series
Multifunction Installation Testers
Reduce test time up to 40 % with Auto Test
Auto Test does 5 required installation tests in one sequence, including
selectable Type A, AC & RCD Auto Test, ensuring compliance with local
installation regulations. It reduces the number of manual connections,
decreases the possibility of making errors and reduces test time up to
40 % from previous Fluke models.
Insulation PreTest
Protect the installation. Avoid costly mistakes.
The new Fluke 1660 Series Installation
Testers are the only installation testers
that help prevent damage to connected
appliances and also allow users to
send test results wirelessly via smartphone
directly from the field.
(1664 FC ONLY)
View test results on your smartphone
via Fluke Connect® mobile app and Data
Management Software (Fluke DMS, sold
separately). Download the free Fluke
Connect app to enable wireless data
transmission and Fluke Cloud™ storage.

Start a sequence of seven critical tests
with one press of the TEST button.
Guards against failures in the field.
Three-year standard warranty.
The Fluke 1664 FC Installation Tester is the only installation with
“Insulation PreTest,” which warns you about potentially serious and
costly mistakes. If the tester detects that appliances are connected to
the system during test, it will stop the insulation test and provide a
visual and audible warning. This helps eliminate accidental damage to
peripheral equipment and keeps your customers happy.
Fluke Connect®, ShareLive™ calling and Fluke Cloud™
Share from anywhere
Save time—eliminate data entry by wirelessly syncing measurements
directly from your installation tester and share with your team using
the Fluke Connect system. Having access to measurements simultaneous at the inspection site and from the office or an off-site location
enables faster decision making and real time collaboration between
team members.
Fluke Cloud™ storage
Retrieve stored results from anywhere
Cloud storage allows you to retrieve stored results whether you are in
the office or in the field to make decisions in real time. Fluke Connect
uses radio-enabled test tools and a mobile app to transfer measurements straight from the field to a secure cloud location, where the data
can be accessed by team members. Plus you can import the data into
Fluke DMS to process and generate certificates.
Key product capabilities
The 1660 Series testers verify the safety of electrical
installations in domestic, commercial and industrial
applications. They can ensure that fixed wiring is
safe and correctly installed to meet the requirements
of IEC 60364 and all relevant local standards.
Fluke 1664 FC
The Fluke 1664 FC is the only installation tester that
protects connected appliances from damage during
insulation tests, and allows you to share your test
results wirelessly by smartphone with coworkers or
customers. Fluke’s patent pending Insulation PreTest
stops you from performing tests with appliances that
are connected to the system during test. This helps
eliminate accidental damage and keeps your customers happy.
In addition, the Fluke 1664 FC offers you the power
of Fluke Connect. Now you can send test results
straight from your Fluke 1664 FC to your smartphone,
and transmit those results to other members of your
team. You can get feedback, suggestions and even
have work orders sent to your job site.
You can also save your test results to Fluke Cloud™
storage. No more writing down data on paper with
the possibility of transcription errors. Cloud storage
gives you a fast, secure and accurate way to storing
all your test data and create test certificates with
Fluke DMS.
Fluke 1663
The ideal tester for professional trouble-shooters.
This instrument is ideal for professional users–highend functionality, advanced measurement capability,
yet it is still easy to use. Operation is intuitive and
easily mastered by all levels of field workers.
Fluke 1662
A solid, basic installation tester. The Fluke 1662 gives
you Fluke reliability, simple operation and all the
testing power you need for basic installation testing.
