I need more calibrating solution, but can only find the liquid type, not the type that came with this meter. Any suggestions?

i use distilled water as i believe (do not know) that ph is 7.0 however the tester only lasted for 18 months.

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.

U can also check out mjlorton on YouTube...he reviews the meter...great for the price.

It's very simple. Contact the factory, ship it to them, they ship it back. If they can't calibrate it they replace it. Each meter has a calibration date specific to that model.

"Standards" solutions can be purchased from Amazon or other chemical supply stores. There is a manual that comes with the meter that describes how to recalibrate the instrument using the standards.

I sure don't! I bought this one and a Sun Master digital and they couldn't read further apart! What we need to find is a calibration solution that works on soil meters, not just water meters.

I came across this site by accident. It explains a lot of things that people might not know will affect their readings. 1) temperature of the liquid 2) how deep the meter is in the liquid 3) how settled the liquid is around the meter, bubbles affect readings. http://www.chemistryland.com/CHM130FieldLab/Lab2/Lab2.html

I don't think it is needed. Just do a check on bottled purchased water. Every so often recheck and see if reading are same if yes no calibration required.

Sounds like it's defective. I never really calibrated mine, but it seems to work fine. Sorry! Send it back

the calibration packet I ordered never made it here so I was unable to calibrate it unfortunately and that is likely the problem....I thought that they may be also calibrated from the factory so I did not worry when my calibration packet didn't come but I guess they must not calibrate at the manufacturing place?

With this meter you would have to grind them up and make a solution and then place a few drops on the testing strip. But just call the company and they will help you.

Not really. The calibration fluid (distilled water) and the test sample are supposed to be at the same temperature. For all practical purposes they will both be at the temperature of the refractometer since they are such small samples.

Hi, I checked the manual it does not list calibration procedures. This is an inexpensive unit and when it goes bad it is time for a new one. I had their previous model for 5 years before it needed to be replaced. Good luck

My advice is ring Fluke, if not, carry out your own question & see what happens, do what you're asking & the meter might likely go to some setting & never work again. My advice, don't play with things you know nothing about. CG

This test method relies on color to get a reading, which makes it difficult to use with anything other than a clear liquid. If you are testing clear water before brewing it will work great. If that is not the case try test strips instead. I've used both with great results for years before finally buying an Oakton meter. I still keep a bottle of this handy : )

I have never calibrated mine and not sure how you would do it short of sending it back to factory. I have compared mine with several other test sets and also the system at my pool store and found it to be very accurate.

I don't know. Meter didn't come with instructions. I was very disappointed in the product myself.
