What once took two people, now takes one
Now one technician can do jobs that would otherwise require two people. Clamp the Fluke 381 around a conductor, remove the display and walk across the room to operate controls or remove protective equipment, all while watching real-time readings.
The iFlex® Flexible Current Probe (included) expands the measurement range to 2500 A AC while providing increased display flexibility. With a cord that runs 6 feet, you can finally measure those tight spaces, awkward sized conductors and disorganized wires.
Other key features
- Integrated low pass filter and state-of-the-art signal processing allows for use in noisy electrical environments while providing stable readings
- Proprietary inrush measurement technology to filter out noise and capture motor starting current exactly as the circuit protection sees it
- Ergonomic design fits in your hand and can be used while wearing protective equipment
- Radio transmitter automatically sets the correct measurement range so you do not need to change the switch positions while taking a measurement
- Three-year warranty
What's in the box:
- 381 Remote Display Clamp Meter
- (1 pair) TL75 test leads
- (1 pair) AC175 alligator clips
- 18-inch iFlex®flexible current probe
- Soft carrying case

Rated 5 out of 5 by Ms Fixit from My most treasured possession I love my Fluke 381 more than my own children (kidding, I don't have kids). I use it daily in my work on boats, both for AC and DC. I never doubt the readings, and the remote display makes me the coolest tech on the dock. It gets borrowed often because it's so awesome. I can clamp the starter or alternator in the engine room, and take the remote display to the helm (except on the REALLY big boats). What usually takes two technicians, I can accomplish myself with my Fluke 381. My Fluke should get it's own paycheck.
My only complaint is I really wish the iFlex did DC amperage. And I wish it were a little smaller. Unlike some other reviewers, I must be lucky because I don't think the battery consumption is bad. I replace them maybe every 2 months, and I use it on a daily basis.

Rated 5 out of 5 by AC Corbin from Another awesome Fluke Product I really enjoy using this clamp meter. I am in the industrial field and use the iflex to calibrate compressors. Without the iFlex, it would be impossible to get a meter around the motor leads inside the motor peckerhead.

Rated 5 out of 5 by Little Mikey from Better than having an apprentice! Way easier than yelling measurements at one another from across the room.
No need to tie up another guy to watch the meter while you make changes.
No need to walk back and forth to check your measurements.
The wireless screen has been invaluable on the work site and at home.
It's not just the convenience, but also the safety factor especially when working on suspect circuits. This is even more true in my industry working transmission protection equipment.
