TDS / EC / Temp Meter — feed your plants with precision
3-in-1 • Backlit LCD • ATC • Auto-Hold- Multifunction, upgraded: TDS (ppm), EC (mS/cm), and temperature in one handheld. Large backlit LCD + auto-lock for fast reads.
- Accurate & reliable: titanium-alloy probe with Automatic Temperature Compensation (ATC) for stable readings across temps.
- Smart power: auto-off after ~2 minutes; Hold saves a snapshot for logging your mix or runoff.
- Wide use: dial nutrient levels for cannabis in soil/coco/hydro; also great for RO/DI systems, aquariums, pools, and general water checks.
- Measurement range: 0–999 ppm (resolution 1 ppm); 1,000–9,999 ppm (resolution 10 ppm, “×10” indicator). Operating temp: 0–60 °C.
Why EC/TDS matters for cannabis
- Prevents over/underfeeding: match ppm/EC to plant stage so salts don’t stack or starve your roots.
- Cleaner flavor: consistent feeds → fewer harsh minerals in flower; better cure and smoother smoke.
- Faster diagnostics: compare feed vs. runoff to spot lockout or salt buildup before leaves complain.
- Scales with you: repeatable mixing → repeatable yields across tents, rooms, and seasons.
Quick EC targets (guide)
- Seedlings/Clones: 0.4–0.8 mS/cm
- Veg: 1.2–1.8 mS/cm
- Early Bloom: 1.6–2.0 mS/cm
- Mid–Late Bloom: 1.8–2.2 mS/cm
- Tip: If using PPM, confirm your meter’s scale (500 vs 700). EC is universal.
Product description
This 3-in-1 digital water tester reads TDS, EC, and temperature with ATC for dependable accuracy. The titanium probe responds quickly, the backlit screen is easy to read in a dim tent, and the Hold function locks readings for notes. Auto-off conserves power. Built for everyday mixing, RO/DI checks, and runoff testing in soil, coco, or hydroponics.

Applications
Cannabis grows (soil, coco, hydro), nutrient reservoirs, RO/DI systems, aquariums, pools/spas, and general water treatment. Verify filter performance, track hardness, and set consistent feed strength for healthier plants and bigger buds.
Pro tips
- RO first, then nutes: measure base water, add nutrients gradually, stir, then re-check EC.
- Log your runoff: runoff EC higher than feed? salts are building up—reduce strength or flush lightly.
- Keep temp steady: nutrient solutions near 18–22 °C read more consistently and keep roots happy.
- Calibrate/verify monthly: use a known solution or cross-check with a second meter for accuracy.
