Certified accuracy, every single test
ISO-certified calibration lab with on-site and remote support. Zero-drift sensors re-certified to ASTM E4 standards, keeping your results court-ready.
Every WIN LAB instrument leaving our facility is calibrated against traceable reference standards. For equipment already in service, our technical desk arranges periodic re-calibration — on-site at your laboratory or via our Howrah service center — so your compression machines, load cells, and sensors stay within tolerance for every audit and compliance check.
Calibration certificates are issued with full traceability, supporting ISO, ASTM, and BIS documentation requirements for civil engineering, geotechnical, and construction material testing laboratories.
