Overall length is around 110 mm including the threaded cap, with roughly 70 mm ahead of the thread; it terminates in a BNC connector for Aqua Medic monitors and controllers.\u003c\/p\u003e\u003ch3\u003eKey features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePG13.5 threaded body\u003c\/strong\u003e — screws into a matching PG13.5 fitting for a sealed, in-line installation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRated to 3 bar\u003c\/strong\u003e — holds pressure inside closed reactors and pressurised pipe runs, where an open probe can't be used.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBNC connector\u003c\/strong\u003e — plugs straight into Aqua Medic pH monitors and controllers, and most third-party BNC-input instruments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact body\u003c\/strong\u003e — around 70 mm ahead of the thread, suited to tight reactor fittings where a longer open probe won't fit.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpec\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer part number\u003c\/td\u003e\n\u003ctd\u003e220.13\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eThread\u003c\/td\u003e\n\u003ctd\u003ePG13.5, plastic\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLength ahead of thread\u003c\/td\u003e\n\u003ctd\u003eApprox. 70 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOverall length incl. cap\u003c\/td\u003e\n\u003ctd\u003eApprox. 110 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePressure rating\u003c\/td\u003e\n\u003ctd\u003eUp to 3 bar\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConnector\u003c\/td\u003e\n\u003ctd\u003eBNC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatibility\u003c\/td\u003e\n\u003ctd\u003eAqua Medic pH monitors and controllers; most third-party instruments with a BNC pH input; fittings using a PG13.5 thread\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch3\u003eSuitable for, and not suitable for\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eSuitable for in-line installation in pipework, calcium reactors and closed nitrate reactors, on freshwater and marine systems, where the fitting takes a PG13.5 thread.\u003c\/li\u003e\n\u003cli\u003eNot suitable for open placement in a sump if you don't have a PG13.5 fitting to seal into — use the L127mm plastic standard probe for that instead.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCare and maintenance\u003c\/h3\u003e\u003cp\u003eImmerse only the tip — a few centimetres — into the measuring medium; the electrode is a wear item and not designed to be fully submerged past that point.

It's the standard size Aqua Medic uses on its own reactors and pH fittings; check your reactor's probe port against a PG13.5 fitting before ordering if it isn't an Aqua Medic unit.\u003c\/p\u003e\u003ch4\u003eCan I run this at full aquarium pressure through a canister filter line?\u003c\/h4\u003e\u003cp\u003eIt's rated to 3 bar, which covers typical reactor and pipe-run pressures. If your system runs higher than that at the probe location, check with the reactor manufacturer before fitting.\u003c\/p\u003e\u003ch4\u003eIs this the same probe as the L127mm standard version, just shorter?\u003c\/h4\u003e\u003cp\u003eNo — it's a different design. The thread and 3 bar pressure rating are what let it seal into a closed fitting; the standard probe has no thread and isn't pressure-rated.\u003c\/p\u003e\u003ch4\u003eHow far in should the probe sit?\u003c\/h4\u003e\u003cp\u003eAqua Medic recommends immersing only the tip, a few centimetres, into the measuring medium.\u003c\/p\u003e","brand":"Aqua Medic","offers":[{"title":"Default Title","offer_id":55285031797027,"sku":"AM22013","price":237.95,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/7236\/5347\/files\/aqua-medic-ph-probe-l70mm-pl-43506875597091.webp?v=1790234314","url":"https:\/\/nicksaquariumoceanariumterrarium.com.au\/products\/aqua-medic-ph-probe-l70mm-plastic-pg-13-5mm-threaded","provider":"Nicks AOT","version":"1.0","type":"link"}
