ExTech stands behind their product

I was tired of using hard-to-interpret test strips for measuring spa water and the low-end pH electronic meter I purchased seemed inaccurate.I can't make a claim to absolute accuracy of the meter; it has the appearance of accuracy with 2 decimal places. I'm assuming the 3-point calibration and temperature compensation will certainly help accuracy. Since using this meter I've been able to maintain good and clear water quality that was previously problematic.It's important to always store the probe wet in the vessel with storage solution. Calibrate the meter and then regularly check the pH with buffer solutions, 4, 7, and 10 pH; you can determine how often is required by checking it at various intervals. Mine holds calibration well over months.The probe is temperature calibrated, I need to leave the probe in the water for at least 30 seconds before the measurement stabilizes.The original meter unfortunately failed (would not power on) after a little over a year of using about 2x / week. ExTech customer service was very responsive and friendly. ExTech kindly sent me a new meter without any charges after I provided them with my Amazon receipt. Hopefully the new one lasts much longer than the original.

A ton of fun

I'm very excited by my new-found ability to measure the PH of all kinds of things. My primary interest in this device was originally for testing the PH of my lawn soil, which I have always suspected is just not right (based on how much difficulty I have growing grass). So I first mixed some dirt with water to measure its acidity - it does appear to be alkaline. Just for fun I also measured the acidity of cider vinegar (guess what: its PH is very low) as well as tap water, tap water with baking soda, and then cider with baking soda (which, I discovered, is how you can make a volcano). All great fun and really neat, I think.The instructions that come with the device are a bit obtuse, or at least I found them confusing. Basically you keep the probe in a cap with a moist piece of sponge, and then you put the probe in different solutions (or, I think directly in dirt, for example). I have been going wild measuring the acidity of all kinds of things, from cottage cheese to single malt scotch. I am attaching some photos of my preliminary research.
