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

Where is fluke 381 made in? What is the guarantee on this 381 clamp meter?
I have a replacement display for my meter and when installed it reads Err id. The display turns on and off with rotary dial. Is there a procedure to match my new display to meter?
Rated 1 out of 5 by Anonymous from Rubbish but used to be a good company bought an expensive 381 clamp meter and the battery catch has broken mainly because its flimsy. but no chance of spare part and it cost over £800 will never buy fluke again

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.
