How do you use this instrument to measure CFM?

You have to measure the velocity (ft/min) and then multiply by the effective area of the grill (ft^2/min)

I tested it against other emfmeters.No documentation is available. I suppose it measures V/m for low frequencies waves, not. radiofrequencies.It worths price se paid!

90 psi but I'm not sure on the cfm been a good tool had no problem with it so far

How did you measure the temperature? Are you sure you measured it at the same point each time?

Check the cfm out put of the compressor to make sure it can provide the cfm of the sander.

I don't know as I do not have a way to measure. It isn't very strong. I have a dish receiver with a slingox and it gets really hot. This little fan moves air (not a lot) but the bit that it moves seems to help a lot. The nice thing about this fan is that it is quiet. I don't hear it over the equipment. So, it my mind it works great for what I am doing. It states it is 45 CFM. 45 CFM seems like a lot to me and I don't know if that is true. But it is working for my application.

I think that this would work very well. I have used this to measure temps on computer processors and heat buildup on electrical components. should do what you want.

I used a cigar hygrometer calibration kit to test it. Inexpensive and accurate way to test the probe for accuracy.

Don't no the answer to the cfm question, but I run my air compressor at 100psi.

No decibel rating but quite compared to other units. This is not nearly big enough for your purpose. You need to draw several thousand CFMS to be really effective. But that's for professionals. You need to provide a return air from outside if you are not going to condition the air or else you are beating a dead horse. Good luck.

I've never tried but I would assume not. I believe it's only meant to measure air temperature.

I own this meter... It will measure in the following units:bar, ozin2, psi, inHg, mbar, mmHg, kpa, kgcm3, inH2O, ftH2O, cmH2O

Are you replacing the old one? If so, see if you can find the cfm (cubic feet per minute) of air movement the old has and compare it to this one.

Cfm is an ambiguous rating and it's difficult to say. I would say 38 would be better as it accounts for compressed volume of air. However if you are using power tools or anything that needs more air I would look much higher or you will see significant pressure drops. Something in the 100's at least or 200's would be ideal. I bought this and switched to a 200+ scfm and I only get a drop of 2-3psi. With this unit I experienced 20-30psi drop at full load.

This is what I bought this unit for. You can use it for "relative" measurements; comparing airflow from one vent to another or comparing airflow before and after a change, filter replacement, etc.

Well it will measure 2 different pressures at the same time. It will then give you the differential in real time. You have to toggle it to see each pressure. It does not show each pressure at the same time. You would run your tubing to whatever place you want to reference pressure. The Dg 700 you referenced is for serious building pressure and tightness testing. This meter is great for reading pressures 1 to 60 inches. The Dg 700 meter is probably good for the low end. Below 1" and a second higher range. Flue pressures are usually below 1" also

most of the time i use it at midium speed and no smell, but i cannot tell you the cfm
