Thông tin sản phẩm

-  K-Patents Semicon Process Refractometer PR-23-MS has a built-in, ultra-pure, modified PTFE flow cell designed to keep all metal and corroding parts from coming into contact with the process liquid. All the wetted parts are made of ultra-pure, modified PTFE. The prism material is sapphire.
-  The PR-23-MS is mounted directly in-line with a pillar or flare fitting. The compact design allows integration to a wet bench or to a cabinet, where the need for foot print area is very low.
-  The dissolved solids concentration is determined by making an optical measurement of the solution’s Refractive Index. The advantage of this principle is that the same instrument can be used to measure any chemical.
-  The PR-23-MS provides a continuous 4-20 mA or digital measurement signal and immediate feedback to the control system, if the chemical is not within specifications. The PR-23-MS is physically small and easy to install in the bulk chemicals dispense, and in point of use chemical blending, spiking and monitoring applications.
-  PR-23-MS is applied to process control and monitoring at the bulk chemical systems and in the in-situ wet process tools (blending, clean, etch and CMP).
-  Compact and mounted direct in-line without filtering. The measurement is not influenced by particles, bubbles, turbulent flow or impurities in the ppm range.
-  Provides a continuous measurement signal, 4-20 mA or digital.
-  Full measurement range Refractive Index nD 1.3200 – 1.5300, which corresponds to 0-100 % by weight. Optional range with nD 1.2600–1.4700 for strong HF.
-  Typical accuracy of 0.1% by weight, e.g. for HCl in water. For multi-component solutions, the measurement signal works as a check-sum.
-  Patented CORE-optics (US Patent No. US6067151): no drift, no re-calibration, no mechanical adjustments.
-  Dual connectivity: one transmitter can operate two sensors. A second sensor can be easily integrated later.
-  Ethernet connection and remote panel for data-logging and remote operation.
-  Process temperature range: -20°C – 150°C (-4°F – 300°F)
-  Fast process temperature measurement by built-in Pt1000 and automatic temperature compensation.
-  ATEX approved for Zone II, area classification EX II 3 G EEx nA II T4.
-  FM approved for Class I, Div. 2, Groups A, B, C and D, T6.
-  CSA certified for Class I, Div. 2, Groups A, B, C and D, T4.
-  cCSAus certified for Electrical Safety, Sensor: Class I, Pollution Deg. 3; Transmitter: Class I, Pollution Deg. 2; Installation Cat. II.
