Verification Products & Viscosity Standards

Certified Standards to Ensure Instrument Accuracy  

Protect your investment between annual calibrations with AMETEK Brookfield Verification Products. Our certified viscosity standards and verification kits are essential tools for laboratories committed to accuracy, quality, and reliability. 

Why Perform Verification? 

Verification checks an instrument’s performance using certified reference fluids without adjusting. It is a pass/fail method to confirm your instrument remains within performance limits.  
  • Use weekly, monthly, or before critical tests 
  • Required when SOPs demand traceability between calibrations  
  • Fast, simple, and cost-effective  
Certified Viscosity Standards 

Available in both silicone and oil-based options, our viscosity standards are accurate to ±1.0% and traceable to NIST. 
  • Silicone Fluids: Low temperature sensitivity, general purpose use 
  • High-temp silicone fluids: Up to 149°C 
  • Oil fluids: Ideal for CAP, KU-3, and RST Instruments 
  • Special order blends upon request 

Viscal Kits: All-in-One Verification Kits  

Everything you need to verify your viscometer or rheometer in one convenient package. Ideal for regular in-house verification, VisCal Kits help maintain confidence in your instrument’s performance between calibrations but are not substitute for annual calibration by a certified technician. 
  • Beakers (glass or plastic) 
  • Certified silicone standard fluid  
  • Cleanup tools  
  • Optional temperature bath lids and cleaning agent  
Tailored Solutions by Instrument 
  • CAP Series Fluids: Specific oils for each cone and temperature model  
  • KU Fluids: Accurate Krebs Unit fluids for KU-3 Viscometers 
  • RST Fluids: Calibrated oil standards for coaxial and cone spindles  
Compliance Support 
  • All verification fluids and kits include NIST-traceable certification 
  • Annual replacement of fluids recommended for continued accuracy  
  • Supports laboratory quality programs and regulatory compliance
