📈 Wiztech Digital PH Meter with ATC: 3 in 1 PH TDS Temp - Accurate Pocket-size PH Tester 0.00-14.00 PH Measurement Range Review

The design of the unit is excellent as is the quality and durability. The backlight is great and allows you to see readings no matter where you are. The reason I ordered this device is that you can use 1 device to measure all your needs instead of using 2 or 3 devices. Unfortunately, I received a defective device from the seller. refunded my money immediately. Excellent after-sales service and quick response to customer inquiries. I will order a new device.

Six packs were supplied, all solutions for three calibration points. New batteries and three additional spare batteries were also included. It was calibrated almost perfectly, but I would suggest doing the initial calibration yourself. The backlit display is great and turns off after 15 or 20 seconds. Seems very accurate, within a tenth of a point or two. .02 +- The TDS meter is in good condition and also factory calibrated. Read exactly like my other TDS meters. Overall a great device for the…

As a farmer, it's vital for me to make sure the water I'm feeding my plants has the perfect pH level. This pH meter offers high accuracy FAST and can be used with pH meters costing $200 or more. Another important feature I love about this gauge is that it has a calibration function that even a caveman can do. If you are about to buy a cheaper product, don't. Do yourself a favor and get this pH meter. Fast delivery. I ordered this device and received it the same week. Comes with extra batteries…

I've tried it in tap water and it showed 7. Dripped a few drops of bleach, still shows 7. Put in vinegar, it showed 6.5. Obviously not calibrated. Calibration solutions were made with distilled water. Put the meter in a pH 6.86 solution and it reads 6.9. Calibrate and it will settle down a bit to 6.86. I wash it off with distilled water and dry it carefully. Put it in a pH 4.00 solution, the meter will read 6.6. If I run the calibration procedure again, the 4.00 solution calibrates to 6.86. Not

Standard pH varies from 0.2 to 0.3 I tried several bottled test solutions and the numbers were far from accurate, especially for a PPM meter. main problem. You can't actually calibrate this block. The instructions say to mix the dry packs that come with it, or to buy special pH 9.18, 6.86, and 4.00 solutions. You dip the pen into the solution and wait for the reading to stabilize. Then press and hold CAL. It then flashes any readings it has as if it is doing something. I had it in solutions 4…

We were given this to test the water coming out of our taps due to the color it can be at times and we just wanted to be sure. The more I read the instructions the better I thought this is good for the pools we have too. We clean and add our own chemicals and it's a lot easier than with strips. Not to mention that we don't have to buy these strips all the time. The readings he gives us broadly agree with what those strips told us. In fact, we did a head-to-head comparison and the results were…
