The strongest, most secure sanitary sight glass available, Viewport's mechanically pre-stressed windows are available in a sanitary clamp design for sight ports in processing applications or inline visual flow indicators.
Unlike some other sight glasses, Viewport sight glasses meet the USP Type 1 standard for pharmaceutical use.
Described as offering the optics of glass and the strength of steel, these glass elements provide a level of safety, and a useful service life, well beyond that provided by conventional tempered glass or plastic in sanitary service. Even at the most extreme temperatures (as high as 536&def;F) or in overpressure situations, sudden, total failure - that involving leakage or explosive shattering of the glass - essentially never occurs.
