VIVOSUN Digital pH and TDS Meter Kits, 0.01pH High Accuracy Pen Type pH Meter ± 2% Readout Accuracy 3-in-1 TDS EC Temperature Meter for Hydroponics, Pool and Aquarium, Black White, UL Certified

Really useful, I think the price is spot on and they have helped remove some of the guess work when it comes to pH and ppm

I had a cheap ph reader that wasn't reliable. With these vivosun ph and TDS meters my garden is blooming! So far these have been very reliable.

Great product once calibration is done super accurate

Always very impressed with Vivosun gear. Both meters are well designed and very accurate. Great purchase.

I purchased the Accuracy Water Quality Tester for monitoring the pH levels in my aquarium and hot tub, and it has exceeded my expectations. Pros: Wide pH Range: The 0-14 pH measurement range makes it versatile for various applications. Accurate Readings: The results are precise, and the built-in ATC (Automatic Temperature Compensation) ensures accuracy regardless of water temperature. User-Friendly: It's lightweight, easy to use, and the display is clear and easy to read. Durable Design: The army green casing is sturdy and has a rugged look that feels reliable. Cons: Calibration instructions could be a bit more detailed, but once you get the hang of it, it’s straightforward. This tester is perfect for household use, whether you’re checking drinking water, hot tub levels, or aquariums. It’s a great value for the price! Rating: ★★★★★

Ist zuverlässig und genau. Und mist die Temperatur des wasser. Empfehlenswert

Bin begeistert funktioniert und wenigstens beleuchtet 👍

El envío tardo más de lo esperado ( aprox una semana más) y además el medidor de ph viene como usado, tiene sales en los pines como si ya se hubiera ocupado antes. Además de que el material y el feeling de los medidores se siente como un producto chino, al que solo le reetiquetaeon con los logos de vivosun

Ich bin mit dem Produkt sehr zufrieden
