Accurate Gas Flow Calibration Primary Standard

• The performance of only the highest level metrology laboratories can now be yours
• Accurate primary standard for labs & industry
• Proven dimensionally-based primary standard accuracy backed by a rigorous uncertainty analysis
• Manufactured to ISO 17025 Standards at a NVLAP accredited lab
• Collected data is directly traceable to NIST
• Surpasses pressure-based secondary methods
• Everything you need to do your own flow calibration
• Less expensive than most popular secondary standards
• Field portable and battery powered
• Suitable for most non-corrosive gases
• Accurate and reliable gas flow readings independent of gas species measured
• Reading options: Single, continuous or burst, with user-selectable averaging from 1 to 100
• Run automatically in continuous mode or operate manually (one flow reading at a time)
• Take up to up to 100 measurements in an average continuous mode sequence

• Easy to use, large LCD readout screen and 23-button keypad
• Generates calibration certificate easily
• Communicate via RS-232, USB, and use free CalSoft® software included
• CalSoft® software automatically acquires flow data for easy data export
• Kit consists of a base and three interchangeable flow cells
• Entire kit is packaged in a Pelican case for safe transport
• Each flow cell has a specific flow range
• Each flow cell is easily changed (no tools needed) within seconds
• Flow cells can be purchased separately; Get started with one, add more later
• Cover a broad set of instrument flow ranges at your facility
• No Mercury or other hazardous materials
• Low maintenance

• All clean gases, non-corrosive, humidity less than 70% non-condensing
• Mass and volumetric flow rate
• Speed from 1 to 15 sec per flow reading
• Accuracy by flow cell range:
  • 500-10: 5 sccm to 500 sccm (0.5 slpm)*
    • Volumetric: ±0.25% of reading
    • Mass: up to ± 0.35% of reading*
  • 500-24: 50 sccm to 5000 sccm  (5.0 slpm)*
    • Volumetric: ±0.20% of reading
    • Mass: ± 0.35% of reading*
  • 500-44: 0.5 slpm to 50 slpm*
    • Volumetric: ±0.25% of reading
    • Mass: ± 0.45% of reading*
• For lower flows, see the CalTrak 800 flows down to 0.5 sccm*
• For higher flows, see CalTrak XL flows up to 1500 slpm*
