Does this meter come with calibration solution, or where can i buy some?

no solution comes with it but amazon has it in 4 7 and 10 the one i got was right on and hasten drifted in 6 weeks just look up ph buffer of calibration solution and a number of them come up hope this helps

I bought this meter, too. I think that you probably have someone else do the work you intended to do if you need a manual for an analog mm. Very simple and straight forward meter that does not require a manual.

Comes with batteries and little screw driver to calibrate it (maybe this model doesn't I don't remember?). It works but get what you pay for and not the best quality, to calibrate it up use calibrate solution and follow directions.

Yes , this meter will do this, plus it is capable of using for many other electrical measurements.I really like mine

We have this test meter for our community well. We fluorinate according to the EPA guidelines. It works well when it is calibrated. You have to have the 1% fluoride solution and the tabs to calibrate the meter. We had the meter for about 4 months and the sensor went bad. The company replaced it immediately at no cost but with the wrong part. It took several weeks to replace it with the right part. It was on B/O for some time. Now that we use it daily I can get an idea of the level we need to be at. It's a field test and they are not 100% but close enough for what we need. When our levels were low the meter just gave a Lo code. It am not confident it would give you a zero reading you may be looking for.

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.

So far, I cannot get it calibrated. They are sending a new replacement meter.

Mine did come with the two calibration packets, but I purchased General Hydroponics Standard Reference Solution when I ordered the unit. I used that to calibrate it when it came and found it to be exactly 7.0. Would recommend getting the extra solution.

Fortunately there is no calibration needed. It works right out of the box. There is no "on" button, the display and pressure sensor are simply activated by pressing the device onto a valve. Works for my car and my bike tires, too. Display turns off automatically after 15 seconds or so. Can't recall the exact time.

Mine did not come with control solution and was reading 20 points below another meter from a different company that I also had. When I read the box, it stated clearly that it did not come with control solution but gave a number to purchase solution. When I called, I was told that solution would be $7.49 and $7 for postal charges. I contacted the seller and they confirmed that this item does not include control solution.

Yes, It's easy to understand. Have had only one opportunity to use the meter and that was just for calibration purposes. It's winter in Chicago but come Spring I imagine it will get plenty of use. It appears to be sturdy.

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.

In order to calibrATE you do need the packets and thew ionized water. Unless you can get a lab to check it against their equipment

The meters are generally always a promo, hence the low price for the meters. The companies make their money selling you their test strips. I really like this meter, but if buying a new one I would check the price per test strip before making a final decision.

No. I had to buy the calibration fluid separately. Best deal I could find was a two bottle combination ($27 more) which really bit the big one because I only needed just one bottle.

I don't know. It's best to buy the ones designed for your meter. Next time you are at your doctor, ask him for a free meter.

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
