This listing is the standard CO-B4 model, not CO-B4+. The manufacturer's CO-B4+ version adds an Integrated Smart Technology (IST) board with stored sensor data and a temperature sensor; do not assume the two versions have the same interface.\u003c\/p\u003e\n\u003cp\u003eThe standard four-electrode sensor needs compatible readout circuitry and instrument calibration; it is not a standalone CO alarm. The manufacturer recommends its Individual Sensor Board (ISB) for low-noise measurements. Match the sensor model, pin connections and instrument requirements before ordering.\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/www.alphasense.com\/products\/view-by-target-gas\/co-b4\" target=\"_blank\" rel=\"noopener\"\u003eCO-B4 specifications and manufacturer documentation\u003c\/a\u003e\u003c\/p\u003e","brand":"Alphasense","offers":[{"title":"Default Title","offer_id":50261376794872,"sku":"WCS-VHTDRA1794","price":338.51,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0849\/0378\/8792\/files\/511ajQOR6TL.jpg?v=1790764938","url":"https:\/\/westcontrolsupply.com\/fr\/products\/co-b4","provider":"West Control Supply","version":"1.0","type":"link"}
