Small Size Big Output Stat Profile pHOx analyzers measure only 12" wide x 12" deep x 15" high, and are light enough for easy transport on a compact cart. But dont let their small size fool you. Stat Profile pHOx analyzers carry enough on-board reagents to perform 7500 tests and contain a full months supply of controls. All Liquid Calibration System A new, liquid only calibration system eliminates bulky gas tanks, gas regulators, gas tubing lines, and humidifiers. A single reagent pack contains all calibrators. This integrated gas and reagent package system replaces up to five individual reagent bottles and two gas tanks with a simple, snap-in reagent package. The single reagent pack also eliminates the need to maintain logs and run both calibration and QC procedures each time one of the bottles or tanks needs to be replaced.
