{"product_id":"trolmaster-wn-9","title":"TrolMaster WN-9 Substrate Sensor Node","description":"\u003cp\u003eThe WN-9 Substrate Sensor Node is the dedicated 3-in-1 probe for the WCS-9 system. Stainless-steel spikes measure volumetric water content and EC; an embedded sensor tracks root-zone temperature. Daisy-chain up to four WN-9 nodes on one WCS-9 display to average the medium and avoid hot-spot or channeling errors. Additional nodes are sold separately from the WCS-9 set.\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eAdd-on 3-in-1 node for the WCS-9 display: VWC, EC, and root-zone temperature.\u003c\/li\u003e\n\u003cli\u003eStainless-steel spikes for soil and high-bulk-EC soilless mixes; temperature sensor is built into the probe.\u003c\/li\u003e\n\u003cli\u003eDaisy-chain up to four WN-9 nodes per WCS-9 display for a trusted average instead of a single-point reading.\u003c\/li\u003e\n\u003cli\u003eVWC 0–100%, EC 0–30 mS\/cm; 5 V \/ 0.1 A node input; 32–122°F and ≤90% RH.\u003c\/li\u003e\n\u003cli\u003eIncludes the ECS-7 12 ft daisy-chain control cable for the next node.\u003c\/li\u003e\n\u003cli\u003ePackage: WN-9 node and ECS-7 12 ft cable.
