High-precision moisture analyser, model Tracer2+

Ultra-high-purity moisture analyser for semiconductor manufacturing processes, inert and speciality gases, component and system testing, and laboratory research applications, with a measurement range in parts per billion. Designed for critical applications involving ultra-pure gases. Featuring NIST-validated P₂O₅ electrolytic technology and detection down to 0.7 ppbV, it offers direct, absolute and drift-free measurement, ideal for processes where moisture is a key determinant of quality and performance.

Its compact design, fast response time (up to 50 per cent faster than its predecessor) and the absence of periodic calibrations make it a robust, reliable and low-operating-cost solution for industrial, electronics and laboratory environments.

Key features:

• Ultra-trace detection: from 0.7 ppbV with optional Heart cell; 1.0 ppbV with standard cell
• Absolute technology: measurement by electrolysis in accordance with Faraday’s Law, with no drift and no need for calibration.
• Fast response: optimised electronics, low-volume regulator and minimal gas path; 50% faster wet-up and dry-
• Low cost: no annual recertification, no permeation tubes or compressed air; minimal maintenance.
• Compact and flexible design: available as a standalone unit or in a 19’’ rack (DUO version for two simultaneous lines).
• Intuitive to use: 5-key keypad, VFD display and guided menus; ready to operate straight from the factory.
• Stability during transport: no need for stabilisation, recalibration or reconfiguration when moving between measurement points.
• Online verification: simply check flow and current to comply with ISO 9001.

• Detection Limit (LDL): 0.7 ppbV with Heart cell (optional); 1.0 ppbV with Standard cell
• Operating Range (for inert gases): Inert Gases: 0 -2000 ppbV; Oxygen: 0 -1200 ppbV; Hydrogen: 0 -500 ppbV
• Accuracy:
  • Inert Mode: 4% of reading or ± 4 ppb, whichever is greater of reading
  • O2/H2 Mode: For use in gases containing substantial amounts of Hydrogen or Oxygen, including Clean Dry Air (CDA). When the value is < 50 ppbV, the accuracy is 6% or ± 6 ppbV, whichever is greater. When the value is > 50 ppbV, the accuracy is 2% of reading or ± 20 ppbV, whichever is greater.
• Cell type (P2O5): RILR, RTLR* NOTE: For sub-ppbV, please specify as Heart cells
