Phase Sequence Indicator Calibration protects people and assets. Incorrect phasing can hide faults and create hazards. Regular calibration confirms your indicator reads correctly every time.
Test4Less makes the process simple and fast. Book online, choose Phase Sequence Indicator Calibration, then complete checkout. We arrange UK collection and return on a day that suits you. Or drop your instrument at our facility for free.
Your instrument is logged on arrival with all accessories. We remove old labels and clean the instrument. Batteries are changed when required. Instruments rest in our climate controlled lab for at least 24 hours. This ensures stable, repeatable results.
Calibration is completed on UKAS calibrated equipment for full traceability. Our laboratory operates to ISO 17025, ISO 9001 and ISO 10012. We calibrate over 30,000 instruments each year. Our engineers train regularly with leading manufacturers.
You receive a calibration certificate with every instrument. We never return a unit with only a sticker. Need a digital copy or a replacement certificate? We provide those at no extra charge.
If your indicator needs a repair, we can help. Our in-house team handles most faults to component level. We confirm costs before work and guarantee repairs. One supplier manages collection, calibration and repair for complete convenience.
