Unparalleled EC and WC accuracy. EC levels are heavily influenced by soil salinity and soil moisture – but high EC levels confuse other sensors ability to accurately measure moisture levels.
TEROS ONE’s new design separates water content and electrical conductivity measurement, eliminating sensor confusion and giving cultivators unprecented WC and EC accuracy — even in extreme irrigation situations.
Precision at extreme salinity levels. When pushing for max yield and quality, indoor cannabis cultivators often push EC levels far beyond what other plants (and other sensors) can handle.
TEROS ONE is the only cannabis substrate sensor capable of precise primary pore water EC measurements up to 20 dS/m – a range wide enough cover even the most extreme drybacks, and then some.
Many substrate sensors were developed for soils, then adapted to work with indoor grow media. Not TEROS ONE. It’s built specifically for indoor substrates, giving growers the flexibility to switch media at a whim without needing to throw out their past data.
Once you’ve installed the TEROS ONE, the data never ends. You’ll get fresh readings every three minutes, 24/7, even if you aren’t nearby. TEROS ONE syncs data automatically to the AROYA platform, so you can check in and get real-time data and visualizations anytime, anywhere.
No plug, just play. There’s just one piece to the TEROS ONE – no ethernet cables, no internet setup, no plugs. Simply use the AROYA app to scan the sticker on the TEROS, and it links up seamlessly.
Repeatable data, grow after grow. The included TEROS ONE alignment tool helps you place your sensor perfectly every time. Intelligent auto-calibration means sensors stay accurate and precise for seasons to come.
