Set the dial to the humidity level you want and the unit switches the connected humidifier on and off to hold the room within that band, using a nylon-loop sensor that reacts directly to ambient moisture rather than a fixed timer cycle.\u003c\/p\u003e\u003cp\u003eTarget humidity moves through a grow - clones and seedlings want it high, flower wants it pulled back down to reduce mould pressure - so a dial-set humidistat lets a grower retune the target at each stage change without touching the humidifier itself. It solves the basic problem of running a humidifier on manual or on a timer, where the room either overshoots into damp, mould-friendly territory or drops back down before the next cycle kicks in.\u003c\/p\u003e\u003cp\u003eThe unit mounts on the wall, ideally at canopy height where the reading actually reflects what the plants are experiencing, and its ON\/OFF micro-switch is rated to drive a compatible humidifier directly without needing a separate relay or contactor in the circuit.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial control\u003c\/strong\u003e across a 10-80% RH range for straightforward stage-to-stage adjustment\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDirect switching\u003c\/strong\u003e of a compatible humidifier up to 2.2A without extra relay hardware\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNylon-loop sensor\u003c\/strong\u003e responds to real ambient moisture rather than a fixed cycle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWall-mountable\u003c\/strong\u003e for accurate canopy-height readings\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePairs directly\u003c\/strong\u003e with the Faran HR-15 and HR-50 humidifiers\u003c\/li\u003e\n\u003c\/ul\u003e\u003cdiv class=\"hcs-specs\"\u003e\u003cul\u003e\n\u003cli\u003eMeasurement range: 10% - 80% RH\u003c\/li\u003e\n\u003cli\u003eAccuracy: ±5%\u003c\/li\u003e\n\u003cli\u003eOperation span: 3%\u003c\/li\u003e\n\u003cli\u003eSwitch capacity: 2.2A\u003c\/li\u003e\n\u003cli\u003eOperating temperature: 10-40°C\u003c\/li\u003e\n\u003cli\u003eSensor type: nylon loop\u003c\/li\u003e\n\u003cli\u003eDimensions: 140 x 95 x 45mm\u003c\/li\u003e\n\u003cli\u003ePower: 220V \/ 50-60Hz, 2m cord\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/div\u003e","brand":"Faran","offers":[{"title":"Default Title","offer_id":53500713468170,"sku":"faran-hr-ehsa-analogue-humidistat","price":89.9,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/7127\/5786\/files\/c8ecf8a805eb940894f73bc7b961e8c43e59ab96.jpg?v=1786377523","url":"https:\/\/hydrocropshop.co.uk\/products\/faran-analogue-humidistat-hr-ehsa","provider":"Hydro Crop Shop","version":"1.0","type":"link"}
