What is the margin of error as determined independently from the manufacturer?

I would assume not very much. But you can contact support for an accurate number. support(at)ozeri(dot)com

I can not answer that but what I did was take it to the nurse where I work and compared their readings to mine using their equipment vs mine. The results were very close. The nurse was happy with the comparison. She said it is not an exact science.

Your guess is as good as mine, but if you ever find out please let me know. If its any help, I'm in cardio rehab, three days a week, and have been for a few weeks now; the results I get from the Ozeri are very simulate to those I get from the therapist using standard blood pressure equipment.

I am sorry it took me a little while to get back to you, I just wanted to be as sure as I could be in finding you an answer. As far as I can tell from the User Manual that came with the product, it says the margin of error is 5 %. My husband has high blood pressure and knows his ranges and I have normal blood pressure and we both use this unit often enough to have faith that it is reading accurate enough to let us know if either of us should go to the doctor because of a way to high or low couple of readings. The manual also gives you tips on when to take and not take a reading. It also states that you need to go to your doctor and find out what your base range is and what he thinks your allowable range should be, but if you are not sure its always good to check with your doctor to be sure. Take care and I hope this helped you.

It is not stated on the products. You will have to write to the manufacturer.

It was installed on a job a while back and it's not convenient for me to measure it. I'm sorry i can't help you.

You need to call the manufacturer for this kind of data. This is a consumer forum.

The manufacturer claims a +/- 5% accuracy. My experience is that at least 7 days is needed to obtain a meaningful average. I actually use 2-3 weeks. Variations can be expected for different periods in the year as well.

I have no idea. If it is important to you, you could contact the manufacturer.

Honestly I don't know. I do know that every recording engineer tells me that these are far and away the best most error free blanks available in the world. The company that reproduces my CDs for me charges a few cents more for this and this brand only. I've used the other brands for different purposes and has had multiple errors but when I use one of these none. As far as they're being a or b ratings? No idea. They are just the best I have ever used.

I can not give an accuracy measurement as I no longer have access to surface plate and height gage. However, compared to my other equipment, I would estimate within 0.001" - 0.002" for the 7" square.

Teac (the manufacturer) provides very precise measurements of their products, e.g. http://www.teac.com/product/cd-h750/specifications/

I copied the specs right from the prod. desc. on Amazon. There are too many to write. Just go to the page and see the info.

I don't know for certain, but there should be some sort of manufacturer ID information.

Resolution and accuracy are two different things. Resolution is the detail you see on the display (i.e. 0.05 degree increments). Accuracy is the error interval in which the device's measurement falls as opposed to the actual physical angle (i.e. plus/minus 0.2 degree or a 0.4 absolute degree interval). So, for example, if your display reads 22.35 degrees, then the actual physical angle of the object is between 22.15 and 22.55 degrees. As you see, the absolute value of the error interval is 0.4 degree. That's less than half a degree of error and suitable for most carpentry applications. It is not, however, considered accurate enough for high precision metal work.

I don't know but the manufacturer or the owners manual may be able to tell you

I'm sorry I do not have an answer for your question. The manufacturer may be the only one that can tell if the numbers are comparable.

Bosch states the accuracy on this model is +/- 1.5mm, or about 1/16th of an inch, under favorable conditons. From the product manual, that means "measurements taken from the rear edge of the measuring tool, 100% reflectance of the target (e.g. a white painted wall), weak backlight and 77 degree F (25 degree C) operating temperature. Additionally a deviation influence of +/_ 0.05 mm/m must be taken into account. " From these specs, at 20 meters, or about 60 feet, you can expect accuracy of +/- 2.5 mm, or about +/- 1/10th of an inch. For typical residential crown molding lengths, you are probably safe to assume you will be within +/- 1/16th inch. These specs are rated per ISO norm 16331-1, meaning they are tested according to Industry standards, which is important when comparing this model to other laser distance meters that don't have this rating.

We do not know. We have never done that. The manufacturer can probaby tell you.

I'm sorry Marcella. I do not know you would have to check the manufacturers web site for that information.
