If you are still using pH test strips, you might want to look into making a small investment in a pH pocket meter. The pH test strips are an inexpensive way to measure the acidity or alkalinity of a solution, but did you realize pH test strips do not provide precise and accurate measurements? Using an organic dye, this coated paper changes color to indicate the presence of acid or base. Easy to use, the litmus papers are only for noncritical measurements. If you want a quick and accurate way to measure, consider a pocket pH meter to test your pH level.
Pocket pH testers
A pocket pH tester is a thin, compact tester that easily slips into your pocket so you can take them anywhere. We recommend the Oakton® EcoTestr™ pH 2+ pocket meter. This handy pH2+ pocket meter easily and accurately measures pH levels and features:
- Large display with a better viewing angle
- Expanded 4-digit dual-line display shows parameters and temperature readings simultaneously
- Automatic temperature compensation ensures accurate reading in varying environments
- Easy-to-navigate interface for quick setup and calibration
- Leakproof cap functions as a sample cup and as a stabilizing base to stand the meter upright
- Rugged IP67-rated housing is dustproof and waterproof—and it floats
- Lanyard attachment makes field measurements more convenient
- Battery level indicator flashes when battery is low
- Batteries are included—ready to go right out of the box!
You don’t have to take our word for it. Here’s what one of our customers said about this handy pH measuring device:
Customer review of the Oakton Ecotestr pH2+
I received the new Oakton ECOtestr pH2+ meter in the mail today, I noticed the cap got quite an upgrade from the previous model, it’s thicker, now has a fill line, and the meter is also equipped with a rubber gasket for a better watertight seal while testing or storing. I removed the cap to add a little probe storage solution in order to hydrate the sensor and let that sit overnight.
The new meter has a much larger main screen to display more information. I do like the battery monitor addition, and if you accidentally leave the meter on, it will shut itself off after 8 minutes of nonuse. The larger display also gives a temperature reading which is nice so you don’t shock your roots with cold water.
Its now time to calibrate and while the new meter allows for 3 point calibration, 2 point works just fine for our needs and any calibration solution will do. I have a couple sample bottles of PH 7.0 and PH 4.0, so those are what we will use today. Calibration of the new meter was easy, you press the calibration button, dip the sensor into your calibration solution and the meter does the rest. There is a CALC icon that flashes when the meter is finding its value, and then a CHECK MARK when its found. After a few seconds, the meter hit its calibration and was done. All I needed to do was repeat the process for both of my calibration solutions to achieve a 2 point calibration, and now I am ready to test my feed.
I already know where my PH lands given the PPM’s I am using, but we check daily and confirm before ever feeding our plants. After a few drops of PH up or PH down depending on your waters buffer, I stir vigorously and dip the meter into my reservoir. The number found its target pretty quickly and there is a new CLOCK icon that flashes, within a few seconds we had a CHECK MARK and I was done. Adjust with PH up or down as needed until you reach your desired PH since we run passive hydroponics, we want to be in the area of 5.8. The new meter works GREAT!
