The 90mm Anderson "Pharmaceutical" gauge has rapidly become the pressure gauge of choice for applications in the pharmaceutical and biotechnology industries. It is designedto meet the most stringent of speci cations, including thosefor accuracy, surface nish, and temperature stability.Applications include process lines and vessels, ltrationequipment, pumps, heat exchangers and other pressure dependent devices or processes. These gauges are particu-
larly appropriate when the process line or equipment will be steam sterilized. The un lled version can even be completely autoclaved while on the equipment.A few of the unique features of this gauge include the electropolished diaphragm and standard re-zero feature, along with a special polysulfone crystal that withstandsautoclave temperatures as well as cleaning chemicals that readily etch other lenses. Each gauge is shipped with a cer-
ti cate of calibration, your assurance that it has beencalibrated to the most exacting tolerances.A new available option provides increased dampening,without oil- lling the case.For complete peace of mind in specifying sanitary pressure gauges that meet or exceed the CGMP's of the Pharmaceuti-cal Industry, specify the Anderson "Pharmaceutical Series". CONSTRUCTION/FINISH Diaphragm: Welded 316L stainless steel, electropolished. Maximum R >
