Hi, I'm having problems with my A/C. I'd like to measure the air temp. coming out of the ceiling vents. I've read that most infrared guns only read surface temps. I've had A?C repairmen over, and they look like they are using an infrared gun.
What can I buy to accurately measure the air temp from the vents?
Probably don't need to buy anything...just hang a reasonable-quality thermometer from the vent in the air flow and you'll be well within accuracy needed.
I've used a kitchen meat thermometer. Just stick it in the vent. If it's a ceiling one, could use a piece of tape to hold it in for a few minutes to get a reading.
It depends on what you're buying at HF and what your usage is. I recently bought a 3/4" breaker bar, for example. From what I can see, it appears close enough to Craftsman or SnapOn so for what I'm using it for, it's a good deal. Usage is to loosen up wheel hub nuts on a car, something I might do once a decade. I also bought a set of impact sockets, and a set of extensions and they work perfectly fine.
On the other hand, if I needed an electric saw to use in trades, I don't think I'd buy it at HF. And for something like a multimeter, I agree buying a Fluke is the way to go. My current one is 30 years old. I bought a cheap one at HF to leave on my boat. It worked OK at first, within a year, it was reading 30% off. I also needed some snap ring pliers, bought a set at HF. The tips, instead of being hardened steel, were so soft that they just bent. But I took them back and they gave me a full refund.
So, I'd say it depends on what you're buying, your usage, and using some judgement.
A friend of mine was a mystery shopper, and often did shops at Starbucks. The company she worked for sent her one of the little thermometers, with the 2 or 3 mm probe, and the plastic probe cover.
She would buy coffee and a baked good and leave, go just out of sight and measure the temp of the coffee. I think they didnt' tell her what the temp should be, for fear that would bias her answer. I think it couldn't be too cold or too hot. When I was there, I would eat the baked good. (She's 50 and still weighs what she did in the 7th grade.)
When she stoppped working for them, I think they wanted the thermometer back, or maybe it was just the stopwatch they gave her for another client.
A lot of her clients went out of business within a year after she was hired. Mystery shopping was their last ditch effort to find out what they were doing wrong. But Starbucks is still going strong.
Yes, indeed. We don't have HF up[ here. Similar outfit is Princess auto. If I need some thing for one time use or don't care if it breaks after couple use, I go to Princess Auto. My idea of buying any thing is best I could afford. Or I save up to get what I want, LOL!
I repair roll laminators for a living, I carry a one of those harbor freigh t ones, a customer went nuts, stating you cant have a gun in a sschool. i p ointed it at my arm and the laser light came on and the customer went nuts till she saw the temperature read out. she believed it was a real gun...... .:):)_:)
