Is the guage accurate

Not sure if it is accurate but used it once and it worked great. It is perfect for emergency situations to get you on the road and someplace to assess the repair need....of course if the tire is blown nothing will work.

There are 3 different reference levels(calculations) that this meter can do. The meter is accurate within what it cam measure. Read the manual on what the meter uses and what uther things can throw off the readings. I have found to to be pretty good meter myself.

I have found mine to be very accurate. Perhaps you did get a defective one and should ask for it to be replaced.

I didn't have any problem. However I sent mine back due to I didn't/don't think it gave me accurate readings.

Who knows how accurate these cheap gauges are... Checked mine with my analog meter: slightly more than 12 volts at the battery - perhaps 12.1 or 12.2. 12 volts at the terminals on the back of the gauge while the gauge read a hair more than 12. Yours might be different of course.

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!

When I purchased this scale it was already pre-calibrated. I just used it right away and have never had a problem with it being inaccurate!

the accuracy is good so far no problems. I like that fact it can put about 10 pounds on it and again measure grams

The gauge is not accurate while the compressor is running. It is not totally accurate, even when it is not running. That is, not as accurate as a good quality dial gauge. I say this because I have several gauges, and all the round (dial) gauges read the same value,and the other ones (bar gauge, digital gauge, and the compressor's gauge) are off by a psi or two.Your best bet is to double check the compressor's gauge with a good quality dial gauge. It will be off by some constant, and once you know what that is, you can correct the compressor's reading by that.

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.

Yes it does, and it is very accurate! I was impressed with the device for the price I paid.

i don't know the guage. it doesn't seem to say. but it is very good quality cable. it looks like a braided material.

It's accurate to the nearest gram as best I can tell. If you are measuring chemicals and doing stoichiometry and it needs to be very precise, I wouldn't recommend a scale like this because it's more intended for quick measurements. For chemistry you'll probably want one of those scales with a hood.

I agree, I do not like "made in China" either.I'm not sure where this guage is made( I'd guess China) but it seems reasonably accurate.I tested it against a known good source and it read wihin +or- 2 lbs. accurate.Not bad for a reasonably priced unit. But, I just wanted to check my source only, not to depend on it for a daily user!

its very accurate. had it tested again the gauges at Sam's club tire dept as my son works there.

As long as it reads 300 to 400 outside it gives me confidence that it is fairly accurate. And it Alway has stayed in that margin outside. In a dark room you can see the infa red pulse every few seconds and seam to adjust corispodingly. Hope that helps.

The meter only has a guage that reads, 0 to 2000 on top and 1 to 10 on the bottom of the line...I only paid less than $4.00 for the meter including shipping from China... It has saved me from over watering. The meter seems to be working ok but I don't know how accurate it is... For a cost of less than $5.00 it can't be too percise...
