is this termometer calibrated at the factory? or would i need to calibrate it myself?

Mine seems to be reading really high, maybe 30% over what I think it should be. I wish there was a way to adjust.

I don't calibrate the meter. It works right out of the box for humidity level. I do not use the ph meter or the light meter. May be you can stick in in vinegar and see if it reads about 3

No and these guages are crap and the company is terrible. Go with autometer and you cant go wrong

You have to calibrate it. It was beyond me. But i had a friend who'd done well in chemistry. He was unsuccessful in getting a reading that made sense, but I blame that more on him, than the reader. I would look for a pre-calibrated meter for someone with limited tech skills. i needed it to test PH in pond water. I have several mud ponds. The PH is a little different in each of them.

Well in a relative sense, the answer is yes. The reason I say that is you have to calibrate it yourself. If you immerse the meter tip into something that you know is 100% saturated, you have the ability to set the meter reading to the maximum, which is 10. Therefore, all other readings should become accurate. This is explained in the instructions that come with the meter.

It is calibrated at the factory. This type of equipment these days are very stable and accurate for what they do. If you need something more precise and more accurate then you probably need to look into lab equipment and not into portable field equipment.

Make sure it's level; just a little tilt changes the distance between the sensors. I used a Swanson Tool CCL001 Cross Check Level, that you can purchase here on Amazon. It's cheap and seems to work good. I used double sided tape and it's still on after six months or so. Checked it with another level to make sure it was reading right.

You should. It's calibrated from the factory but you won't know how long it's sat in some warehouse. If you care about getting the most from what you're weighing than definitely get the calibration weight.

I checked it with my other meter and it appears to be already calibrated. Both of my meters match.

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 would be wary of the accuracy, there are "dead spots". I ordered two of these and both of them had a "dead zone" of about 6 degrees (from 76F-82F) where it would show it was 76 until it suddenly spiked to 82.

You should calibrate any thermometer but if you are getting weird readings try changing the battery. Acurite recommends a basic alkaline not a heavy duty. This worked for mine.

There is no initial calibration needed and I don't find anything regarding instructions on how to calibrate it should there be the need to in the future. I am assuming that since it works as most digital scales do, measuring changes in electrical resistance distributed to load cells, calibration is performed at the factory and would need to be performed by the factory in the future if there was a need to do so. I have had other digital scales which operated the same way and lasted for many years. It measures the same as a mechanical scale I have so I believe it is accurate from the factory. The only way to tell for sure is to locate a standard and periodically check to ensure it is calibrated against that standard.

I have not yet encountered this problem. I would think re-calibration would have to be done by service technician people. I do not find any measurement "0 in" feature in on my unit, such as what my digital micrometer has. To be accurate, a definate test fixture would need to be used for calibration.

Mine was pretty well calibrated (within .02g for the 500g weight). It really depends on how accurate you want it to be. It is not "self calibrating". A set of calibration weights will help keep your scale as accurate as it can be.

you have to find the duplicate unit, i think sears sells, then use their on line manualI hated it at first then i realized the logic, one button controls both temp sides and to calibrate use stired ice water with both probes in the water, stir fast with lot of ice and set at 32 f

In order to calibrate such a probe, the manufacturers would have to add a calibration potentiometer to the circuit. Without opening up mine I doubt it was made for field calibration. You can test the accuracy of the device by filling a 8 oz glass with ice and water. Allow to set for 3 to 5 minutes and insert the probe. That water ice mixture should be 32 deg F. what your device shows should be considered where 32 is. That means if your device shows 29 you are off by -3 deg. this should not be a big deal a plus or minus 2 degs. Also, as the battery degrades, it will affect accuracy. Test your probe once a month and replace battery based on any drifting away from what you started out. I have used these types of probes for many years in hvac and they fail long before I lose accuracy.
