Precision Lab Testing Accuracy
We recommend testing transformer oil at least once every 6 to 12 months, depending on the criticality and load of the equipment. Regular testing helps detect early signs of faults, moisture, or insulation aging before failure occurs.
Our AI-powered ERP processes most reports within 24 to 48 hours of sample receipt at the lab. You’ll receive results via email and through your secure online dashboard — fast, accurate, and hassle-free.
Our sampling is fully digital and traceable. Each bottle is vacuum-sealed and tagged with a unique barcode, scanned using a mobile app linked to your equipment’s exact functional location — ensuring zero mix-ups and full tracking from site to lab.
