Keep your water quality on track without the lab coat. This pocket-size digital pen reads TDS in ppm and temperature, so you can confirm RO output, dial in shrimp-safe remineralisation, or spot creeping hardness before it affects your scape. A simple HOLD function lets you lock the reading, then note it down without rushing.
Range is 0–999 ppm, ideal for aquarium use, and the probe tip is designed for quick, stable readings when dipped into a glass, beaker, or tank. Power comes from 2 × LR44 (1.5 V) button cells. Slip it in your maintenance caddy and you’re good to go.
