{"product_id":"trolmaster-wcs-9","title":"TrolMaster WCS-9 Substrate Sensor Set","description":"\u003cp\u003eThe TrolMaster WCS-9 is a 3-in-1 substrate sensor set for Aqua-X, Hydro-X, Tent-X, and Green-X. It measures volumetric water content, EC, and temperature in soil and high-bulk-EC soilless media. A redesigned multi-node architecture daisy-chains up to four WN-9 sensor nodes into one display and averages the root zone so a single probe cannot misread a hot spot or channel. That average drives TrolMaster Feed-on-Demand irrigation.\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e3-in-1 root-zone set: volumetric water content (0–100%), EC (0–30 mS\/cm), and temperature.\u003c\/li\u003e\n\u003cli\u003eDisplay plus one WN-9 node included; daisy-chain up to four WN-9 nodes and average the medium instead of trusting one probe.\u003c\/li\u003e\n\u003cli\u003eFeed-on-Demand irrigation trigger with 10-second demand interval (normal read every 1 minute).\u003c\/li\u003e\n\u003cli\u003eWorks with NFS-1\/2\/3, HCS-2, TCS-1, and GCS-1.
