Fluke CNX 3000 Wireless Digital Multimeter

Fluke  |   Mfr# FLK-CNX 3000   |   Item# DO-20044-00

$349.95 USD/EACH


  • View live measurements from multiple modules simultaneously and remotely on a single screen
  • Log function on modules minimizes wait time when isolating intermittent events
  • Recording capability allows you to capture up to 65,000 sets of min/max/avg readings over single or multiple logging sessions
  • Identify up to ten placed modules with meter or PC and select only those needed
  • Increase safety by taking readings in a separate location away from the point of measurement
The Fluke CNX 3000 suite of wireless test tools makes your job easier by allowing you to conveniently take measurements remotely and wirelessly, increasing productivity by taking measurements quicker and solving problems faster. The wireless digital multimeter allows you to display readings from up to three remote wireless modules, in addition to the multimeter, from up to 65 feet (20 meters) away. Easily expand the capability of this system by connecting to your PC and view up to ten measurements simultaneously.

This wireless system provides you the ability to set up your measurement once and take readings as often and whenever you want. This allows you to work with fewer interruptions by recording multiple sessions before downloading data. The data can be viewed and recorded on the meter, and saved to your PC in .csv format for easy viewing and further analysis with the PC 3000 adapter (order separately).

Select the required wireless digital multimeter and optional module(s) to complete your wireless system. The wireless-enabled modules measure AC current (choose a standard clamp or flexible clamp to measure AC current), temperature, and AC voltage. Mix and match the modules, or select from preconfigured kits (on page 0000) for additional convenience based on your unique application requirements.

  • Q:

    What is the wireless range and protocol used? Bluetooth? 802.11x? MESH?
    Asked on 11/7/2012 by Scott from Ponca City, OK

    2 answers



      Wireless range is a maximum of 1000' line-of-sight under perfect conditions. It uses a proprietary protocol that was developed before any of the ones you mention were invented.

    • A:

      I Think the answer above had a extra digit. The spec is listed as 20 meters (which is about 60 feet), and with the one I have I can get about 100 ft in ideal conditions.

      The protocl is FWCS, per a YouTube video with some Fluke guy. I think he said is used the same frequencies as Zigbee, but it wasn't zigbee.

  • Q:

    Can this check temperatures in a furnace wireless?
    Asked on 11/5/2012 by None

    1 answer



      According to Fluke, "CNX t3000 includes CNX t3000 type K temperature module, 80PK-1 type K thermocouple wire, TPAK magnetic hanger, and two AA batteries." This transmitter module takes a standard K thermocouple, so you can place the transmitter in the habitable zone and extend a standard type K T/C into the furnace as required. We sell K T/C's that will perform this service in case the supplied standard T/C is not adequate for your particular application.
