{"product_id":"neptune-systems-pm1-module","title":"Neptune Systems PM1 Module","description":"\u003cp\u003eThe PM1 module adds pH or ORP (redox) monitoring — plus a temperature sensor port and six digital I\/O inputs — to your aquarium controller system. Whether you use a pH or ORP probe, the module gives you real-time water chemistry data, logs it automatically, and lets the controller trigger outputs based on those readings (e.g. CO₂ solenoid for a calcium reactor, ozone generator, or alarms). The six extra I\/O inputs make the module flexible: you can connect float switches, leak-detection sensors, sump sensors or other triggers for automated responses. It integrates seamlessly via AquaBus and is compatible with all systems in the same controller ecosystem.\u003c\/p\u003e","brand":"Marine Fish Shop Online","offers":[{"title":"Default Title","offer_id":52047981674837,"sku":null,"price":109.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0967\/2278\/0501\/files\/pm1module.webp?v=1765293625","url":"https:\/\/marinefishshop.uk\/products\/neptune-systems-pm1-module","provider":"Marine Fish Shop Online","version":"1.0","type":"link"}
