{"product_id":"industrial-9050cr-controller","title":"Industrial 9050CR Controller","description":"\u003cdiv\u003e\u003cp\u003eA compact, dual‑channel +GF+ Signet 9050CR Conductivity\/Resistivity Controller monitors and controls conductivity or resistivity of aqueous solutions from a 1\/4‑DIN enclosure with a front panel rated for NEMA 4X\/IP65 environments. The LCD displays conductivity, resistivity, and process temperature (°C), along with relay activation status and setup messages to guide configuration. It accepts +GF+ Signet 3‑28XX‑1 series sensors for input and is compatible with sensors such as 3‑2819‑1 (0.01–100 µS), 3‑2820‑1 (0.1–1000 µS), and 3‑2821‑1 (1–10000 µS); each sensor variant specifies its own fitting, maximum pressure, and maximum temperature (3‑2819‑1 and 3‑2820‑1: up to 100 psi\/6.9 bar and 212°F\/100°C; 3‑2821‑1: up to 200 psi\/13.8 bar and 248°F\/120°C). Temperature compensation is provided by a PT1000 element, and the dual channels can operate independently or be coordinated to control two inputs. This makes the 9050CR suitable for processes requiring reliable conductivity\/resistivity monitoring in applications such as water treatment, chemical processing, and rinse-water workflows. \u003c\/p\u003e\u003c\/div\u003e","brand":"SIGNET","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46267988017386,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-016.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/industrial-9050cr-controller","provider":"GTG Hardware","version":"1.0","type":"link"}
