Overview
What is Planetary Mixer Calibration?
Cement and mortar test methods prescribe exact mixing regimes — and the planetary mixer's defined paddle and orbital speeds are part of the method. IS 10890 (Specification for Planetary Mixer) fixes the low/high speed pairs used across IS 4031-family testing; belt wear and control drift move real speeds away from spec, changing mortar consistency and downstream strength results.
Global Lab measures true paddle rotation and planetary orbit speeds with traceable non-contact tachometers at each speed setting, checks paddle-to-bowl clearance with gauges, and certifies conformity with as-found data under our ISO/IEC 17025 system.

NPLI-Traceable References
Reference standards with unbroken traceability to national standards.
ISO/IEC 17025 System
Calibration under our accredited laboratory quality system.
Rotation + Orbit
Both motions measured independently at each setting.
Fast Turnaround
Certificates in 2–4 days — minimal instrument downtime.
As-Found / As-Left Data
Both states recorded, so drift since last calibration is visible.

Test Procedure
How the Planetary Mixer Calibration is Conducted
- 1
Mechanical Inspection
Paddle condition, bowl seating and drive noise are inspected as-found. - 2
Paddle Speed Measurement
Paddle rotation is measured with a traceable tachometer at each speed setting. - 3
Planetary Speed Measurement
Orbital (planetary) speed is measured independently at each setting. - 4
Clearance Check
Paddle-to-bowl clearance is verified with feeler gauges against specification. - 5
Certification
Speed table, clearances and verdicts are issued via Autovity QLMS.
