It uses a calibrated absorption burette and caustic absorption method to determine the percentage of CO₂ in a gas sample.\u003cspan class=\"PDq2pG_selectionAnchor\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp dir=\"auto\" data-start=\"550\" data-end=\"986\"\u003eDesigned for beverage production, breweries, laboratories and quality control applications, the instrument provides a straightforward and highly accurate method of checking CO₂ gas purity. The improved design eliminates the confusing hose connections, multiple cocks and awkward handling associated with older gas purity testing methods, helping make routine testing cleaner and easier to perform. \u003cspan class=\"contents\" data-content-reference-start=\"949\" data-content-reference-end=\"966\"\u003e\u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp dir=\"auto\" data-start=\"988\" data-end=\"1313\"\u003eThe tester consists of a calibrated absorption burette and caustic reservoir mounted to a polished PVC frame. The 10102 absorption burette supplied with this configuration is graduated in 0.01% increments across a 99–100% range, allowing very fine measurement of high-purity CO₂\u003c\/p\u003e\n\u003cp data-section-id=\"xrf996\" dir=\"auto\" data-start=\"2232\" data-end=\"2247\" class=\"PDq2pG_selectionAnchorContainer\"\u003e\u003cstrong\u003eHow It Works\u003c\/strong\u003e\u003cspan class=\"PDq2pG_selectionAnchor\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp dir=\"auto\" data-start=\"2249\" data-end=\"2469\"\u003eA sample of the CO₂ gas being tested is introduced into the absorption burette and used to displace the air from the tester.
