TrolMaster WN-9 Substrate Sensor Node

The 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.

Features

• Add-on 3-in-1 node for the WCS-9 display: VWC, EC, and root-zone temperature.
• Stainless-steel spikes for soil and high-bulk-EC soilless mixes; temperature sensor is built into the probe.
• Daisy-chain up to four WN-9 nodes per WCS-9 display for a trusted average instead of a single-point reading.
• VWC 0–100%, EC 0–30 mS/cm; 5 V / 0.1 A node input; 32–122°F and ≤90% RH.
• Includes the ECS-7 12 ft daisy-chain control cable for the next node.
• Package: WN-9 node and ECS-7 12 ft cable. Ships 6.30 × 3.39 × 3.39 in, 0.66 lb.
