{"product_id":"r718y","title":"R718Y","description":"\u003cp\u003eClogged filters push up fan energy use and degrade air quality; the R718Y measures the pressure drop across a filter or duct section so replacement can be scheduled on condition rather than by calendar. It reads differential pressure from -500 to +500 Pa with 3% of reading ±0.1 Pa accuracy, plus temperature, via two 6 mm hose connections. Two AA-size lithium batteries provide around 3.8 years of 15-minute reporting over LoRaWAN, and the IP40 unit attaches to ductwork or plant with a magnetic base. Netvox lists duct filter monitoring as the primary application; it also suits room-to-room pressure checks in clean or isolation areas and verifying air-handling unit performance.\u003c\/p\u003e","brand":"Netvox","offers":[{"title":"Default Title","offer_id":50169456001281,"sku":"R718Y","price":0.0,"currency_code":"AED","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0834\/2224\/9217\/files\/R718Y_7b8703db-1265-4f78-b879-9176c1bf7d5b.jpg?v=1790322440","url":"https:\/\/store.subnetik.ae\/products\/r718y","provider":"Subnetik","version":"1.0","type":"link"}
