  • The Fluke CNX™ 3000 HVAC System lets you work on electrical panels faster, safer, easier with remote current and temperature modules.

    Connect your CNX a3000 AC Wireless Current Clamp Module to your test point, and view the results up to 20 meters away on the CNX Wireless Multimeter. Plus, you can connect the CNX t3000 K-type wireless temperature module and view remote temperature measurements.

    You'll save time, with less run-around collecting multiple measurements. Use multiple modules for measurements on three-phase systems. Or use as a stand-alone measurement tool or combine with other CNX modules as a system for multiple measurements.

    From short distances, you can even view readings from modules through closed electrical panels. Plus no more writing down data as the CNX remote modules captures up to 65,000 sets of time stamped min/max/avg readings, using the optional PC adapter. CNX wireless test tools also offer increased safety by letting you view readings in a separate location from the test point.

    Now you can take readings on moving machinery, with only the measurement module in harm's way.

  • Your CNX 3000 HVAC System provides measurement of all common electrical and temperature parameters.

    The CNX 3000 Wireless Multimeter offers:

    • True RMS AC and DC voltage measurements to 1000V
    • True RMS AC and DC current with 0.01 mA resolution
    • Continuity, resistance, diode test, capacitance and frequency measurements
    • MIN/MAX Recording
    • CAT III 1000 V; CAT IV 600 V; IP54

    The CNX t3000 K-Type Wireless Temperature Module offers:

    • Temperature measurements from -200 °C to 1372 °C
    • ± 0.5% accuracy
    • Memory recording up to 65,000 readings
    • Backlit LCD display; IP42 with thermocouple attached

    The CNX a3000 AC Wireless Current Clamp Module provides:

    • True RMS AC current measurements to 400 A
    • 2% accuracy to 100Hz, 2-1/2% accuracy to 500Hz
    • Memory recording up to 65,000 readings
    • Backlit LCD display
    • CAT III 600 V; IP30

    The CNX wireless system can track up to 10 measurement modules simultaneously, with results sent to a PC for detailed analysis.

  • CNX 3000 Wireless Multimeter

    For all specifications: accuracy is specified for one year after calibration, at operating temperatures of 18 °C to 28 °C, with relative humidity at 0 % to 90 %. Accuracy specifications take the form of ± ([ % of Reading ] + [ Number of least significant digits ]).
