How accurate is the meter?
1421131
I have done repeated measurements at the same time on the same drop of blood, several times. The measurement error seems to be about 5%, e.g. I might get readings of 95 and 100 from the same drop of blood using two different test strips (as you can't reuse the strips). How accurate it is, I don't know--I need to buy the control to assess that.

This is my first meter. I realized that I got 3 different number, when I did it 3 times. And I don't know how accurate other meters are.

I have seen up to a 10 point spread. The best use of the meter is to estimate what foods you can eat and to check big bench marks of blood sugar (70-80 fasting, 80-100 normal, 100-140 high, 140-200 pre diabetic...)

My answer would be a big YES... it seems very accurate and I often compare it to the one my Step-mom uses daily at her Hospital job.It's consistant within 2 or 3 percent. My husband and I are in our late 50's and we both use it once every morning...again after our daily workout at the Gym...and again a few hours after the Gym workouts. six times a day and it has never failed to give good solid readings.

Absolutely! And it pretty accurate on the 10A scale. Just connect leads to +10 jack and GND jack. Set meter on 10A scale. Be careful here. Set meter up before applying current. [because when you turn selector switch, you do go through other scales/ranges that might exceed a scale/range.] Remember! Current is usually a series measurement. The meter is inserted between source and load.Also, there is a caution in the manual about exceeding 10A and 10A in general. Normally you select meters and ranges such that you operate in the middle to upper 75% of a scale. Usually, you obtain the best accuracy here. This scale isn't fused! Absolutely!

No it is not. But it has been very dependable for us. You should calibrate at least once a week. The cost of this meter is cheaper than a higher end units probe. be careful the probe is not a water tight. Hope this helps.

I have this meter and I do use it every day. As a matter of fact I have three. I love that it takes a wheel and the wheel has ten test strips on it. However, I can't vouch for its accuracy. I have taken my blood one right after the other with two different meters and they are as much as 20 points different. I still use it though.

We have used our Rainwave Flow Meter for almost a year to measure the amount of water we add to the tanks on our RV. Before using it, we checked the accuracy several times by filling 1 and 5 gallon buckets. The Meter was only off by a minuscule amount. After several uses, we checked the accuracy again, and it was pretty much the same as the initial testing. I would say that you could definitely use it to measure it from the faucet, but I have no idea how long it will remain accurate with the amount of water you will be sending through it while pressure washing. It's worth a try for $17.00. If it fails after awhile, you may require something a bit more durable.

It was not very Accurate. Also... my third purchase was a bad unit. Neither the seller nor the maker would respond... not even to the BBB. Be careful. The working two have lost most battery life after a year. Good luck.

Mine seems to be accurate. I've checked it against our indoor thermometer in a different room.

The owners manual says it is accurate to 100' or appx. 30.5 meters. I personally have not used it for measuring that great of a distance but I can tell you it is a great tool for the price. I often work inside building with poor lighting conditions and the back lit display is great. The accuracy seems to be spot on. One of the best time saving tools I have ever purchased. I wouldn't know what to do without it!

It is very accurate. Just make sure you get one in the correct range you need. I may need another one due to this fact. The levels I check are at the very top of the range of the refractometer i bought.

Yes. It's a nice meter that kept working even though I sent it through the dishwasher. Please do NOT try that stunt yourself. I didn't mean to!!

I would say it is fairly accurate. However, I don't really let my motorcycle battery get that low to really determine how accurate.

Cannot answer your question exactly but suggest you look at the following link - https://www.youtube.com/watch?v=ZoeUgMFLyAw.It will give you a GOOD insight. For my use the meter is adequate.

I can't verify the accuracy except that it matched those of others with whom I've compared mine against. It will read from 0.1 lux to 200,000 lux. I use mine in an Integrated Sphere to measure flashlight output in lumens down to the hundreds of a lumen. It's a great meter!

I just got it and I've only used it twice, but yes it's accurate...although one of those times it did take me on a slightly longer route which used wider streets. I assumed that was by design because I told it I was driving a 40' motor home.

Yes. And it pretty accurate. I've tried two different thermometers and the ridings was the same

This meter was my second one as the first one had to be charged about every other day. As far as numbers being off I have had no problems with that. It works well and I have to charge it about every 2 wks. So I am pleased with it. Maybe you are like me and have a bad one?? Maybe replace it?
