Rated 1 out of 5 by from These are not good I work at a large institution. My department has 8 of these and none of them tell the same thing. Many are wildly different from the others and there is no way to know which one is right and it costs as much to send it for calibration as it cost to buy in the first place. I'm guessing Fluke doesn't want to touch these things because they are junk so they are charging a fortune to fix them hoping no one will take them up on it. This is the most expensive piece of junk I own. .

Rated 1 out of 5 by from Might work, might not We have one of these units that seems to function properly so we purchased a second unit. We sent the new unit with calibration certificate to our calibration lab to have is registered and it failed calibration. Fluke's remedy for a new unit is to sell us another unit. No thanks, we'll be changing brands

Rated 1 out of 5 by from Garbage Only about a year old and was babied and protected well between uses. Rh is off by 10% on avg rendering it totally useless as an hvac tech. Can't be field calibrated, fluke wants $865 for calibration. Unacceptable. This should have came calibrated and held for more than one year. They are not accurate and long lasting like they claim. So upset with fluke especially since I've been a customer for 25 years for electrical meters. Don't buy this. It's trash

Rated 1 out of 5 by from Don't try and get it calibrated or repaired This little meter we use once a month to check humidity levels in agricultural drying facilities. This meter has been in a carrying case and never abused. After 13 months it won't turn on. We find out the warranty is expired and tough luck buy another unit. We were disgusted. Additionally the service department was dismissive and rude. Don't buy this. It's an imported device slapped into a Fluke branded case.

Rated 1 out of 5 by from Out of spec after 3 years Our plant engineering team bought a couple of these for checking humidity in our paint shop. When performing annual verification using our Fluke 5128A standard, it was reading 23.3%RH @ 20%RH & 23°C. Spec is +/- 2.5%. No adjustment available. Seems quite expensive for a disposable meter.

Rated 1 out of 5 by from Disappointed The 971 seems to be a disposable meter. Our company purchased three of these meters and all three meters can not be recertified/recalibrated. As a Commissioning Engineer who focuses on HVAC system testing and investigates IAQ complaints, it is imperative the instruments I use are verifiably accurate. To be fair, I have not attempted to send the meters to Fluke for calibration. A local vendor has been able to certify and calibrate every other meter we own (multiple manufacturers including Fluke) and trust them when they say the meter is out of calibration and not repairable.
