• Unique microsphere method of sieve calibration
• Mean aperture sizes traceable to NIST and NPL
• Measure over 1 million apertures per minute
• Typical calibration time of about 1 minute
• Method analyses over 80% of the sieve surface
• Accuracies and repeatabilities better than 1µm
• Results independent of sieve shaking method
• Single-shot bottles remove operator bias
• No need to send sieves away for calibration

Quick and simple to use!
Empty the complete contents of a bottle onto the sieve and shake evenly over the surface for 1 minute. Calculate the percentage passing and read off the mean aperture size from the calibration graph.
