Easy to Use pH Meter
I am happy to report that this is so easy to use. I was able to calibrate the meter easily with the provided solutions and directions. There are just three buttons and the screen is easy to read. The meter even came with four extra batteries. (The batteries are LR44 batteries). The best part is that I am able to use this meter for some of my other interests (like canning, fermenting, and cheesemaking), and hopefully it will help me to become better in these areas as well.
The meter is well made. It comes with a protector for the probe, the solutions for calibrating, and a solution to keep the probe functioning correctly. Instructions are clear and easy to understand. Definite 5 stars.
Works as intended
I wasn't sure how something marked for a solid would do when testing in just liquids, but this thing has rocked it! It comes with calibration/verification solution (4.0 and 7.0) so you can test it periodically and calibrate when necessary; mine has drifted slightly (0.1) over a month but it maintains calibration fairly well. I recommend this to anyone sick of the standard PH pens dying off, I wash mine off with RO water at the end and use the provided storage solution and haven't had the issues I've seen with others.
Super Duper Accurate
This meter is very accurate. My friend brews craft beer and owns a very expensive Milwaukee pH meter and this pen was within 0.1 to 0.2 accuracy when tested on both RO and Tap. The best part of this pen is that it comes with a moisture cap and storage solution to preserve the bulb, ensuring accuracy and longevity. I have ruined many PH pens through the years by letting the bulb coating dry out, but this pen seems to solve that problem. I highly recommend this pen as it is very accurate and designed to last.
Good tool for home canning
I was concerned about the PH of my canned goods so I ordered this meter. I did have to read the manual and remember a bit of High School lab procedures but it was straight forward to calibrate and then easy to use as a measurement device.
This will require some time investment to get started but well worth the effort. Now I know my canned goods are at the correct PH for proper storage.
Bright Display
This tester does offer a lot of features. I really only needed it for dissolved solids but found the other features handy.
The display is large and bright. That makes it easy to read. I do know that the temperature is accurate. The TDS was close but not exact when I compared the readings from a different tester. When I tested reverse osmosis water, there was a difference of 10-15 points. I don't think that was a big deal. The other tester could be off. I tested bottled water and the difference was less.
I can see the value in this tester if you have a pool. The other functions are useful for pH and SALT.
This tester will find a useful place.
Very Accurate
certain it would be fantastic if you were doing fermentation. I got it to monitor the pH of dyes and lake pigments for my handmade watercolors, some of them (especially the anthocyanin based plant pigments) are very sensitive to pH and require very specific balancing to get colors I want. I was using strips but kept running into problems where the very concentrated dyes would distort the readings due to it dyeing the paper.
After calibrating I wandered around the house testing various things against my strips and it was perfectly accurate, with the addition of a thermometer I can check the temperature on various dye baths that are temperature sensitive as well, it is a perfect tool for what I need. The instructions were really easy to follow and I appreciate the extra batteries. If you need a pH tester then I cannot recommend this tool enough, I love it and it will have a permanent home in my dye making supplies.
Wow it Works!
Wow it really works! I was using the PH strips to measure PH, and I absolutely love being able to use this digital pH meter instead. Its 0.01 resolution and high accuracy make it an essential tool for ensuring precision in various food preparations. I feel good knowing the digital readout is so accurate, leaving very little guesswork in matching colors on paper strips.
It's a must-have for anyone serious about precision in preparation.
Very simple to use
This YIERYI Digital pH Meter for Food, 0.01 Resolution High Accuracy Food pH Tester is easy to use. It is easy to calibrate with just the push of a button. It even comes with the ph calibration solutions. I use this for testing the ph of foods as I can them to make sure everything is correct. I love this ph meter because the end is a special type of durable plastic, better than the regular ph meter probe. Cleaning due to the type of probe end is easy too. Overall this is a great PH meter for cooking purposes.
Pro Quality PH Meter
This PH Meter is Built Vary well. It comes with an extensive Manual, Both 4 and 7 pH Calibration Solution as well as Storage Solution to Protect the Probe in Storage. It also comes with Extra Batteries, Microfiber and Cleaning Brush. The Build Quality is Superb for the Price Point.
The Instructions are Detailed on the Operation, It also Includes a Reference Chart to what Food Standards are supposed to be.
This pH meter gets a solid 5 Star Rating
