Easy Garden BT300 Bluetooth pH & TDS Meter – Smart App Control, 32cm

The Easy Garden BT300 Bluetooth pH/TDS Meter (32 cm) is the ultimate smart tool for modern growers, designed to give you absolute precision over your nutrient solution directly from your smartphone.

Are you tired of guessing your nutrient levels and risking your entire harvest because of inaccurate water readings?

Using cheap, uncalibrated pens or messy liquid drops is a recipe for disaster. One wrong reading can lock out essential nutrients, stunt your plants' growth, and turn months of hard work into a frustrating, low-yielding nightmare. Plus, manually writing down your daily parameters is a tedious chore that takes the fun out of growing.

Enter the Easy Garden BT300. This smart device eliminates human error by instantly sending highly accurate pH, TDS, and temperature readings straight to your phone via the "Tuya Smart" app, ensuring your plants always get exactly what they need to thrive.

Frequently Asked Questions

Does the meter turn off automatically?

The device has an auto-shutoff feature to save battery, BUT please note that as long as the Bluetooth is actively connected to your phone, the meter will not turn off automatically.

Personal Experience of Pevgrow’s CEO (Alan)

I've tested countless meters over the years, and the Easy Garden BT300 has quickly become one of my favorites for daily reservoir checks. The 32 cm length is an absolute lifesaver when I'm working with deep 50-liter tanks—no more dropping tiny pens into the water! I love having the Tuya Smart app open on my phone while I slowly add my nutrients; seeing the TDS and pH adjust in real-time without having to squint at a tiny LCD screen is incredibly convenient. Compared to basic models, the stability of the readings is fantastic. Just remember to disconnect the Bluetooth when you're done so you don't drain the 9V battery. If you want to modernize your feeding routine and take your yields to the next level, this is the way to go.
