Choose Combined (Loop/RCD Testers) Calibration to keep readings reliable and compliant. We check your loop and RCD functions against trusted standards. We use UKAS traceable methods in an ISO/IEC 17025 accredited lab. So your data supports audits and on-site decisions.
Booking stays simple. We arrange collection across the UK. You pack the tester with all leads. We then calibrate, certify, and return it ready for work. Turnarounds stay quick to reduce downtime.
Our process adds confidence at each step. We inspect the unit and accessories, verify loop ranges with known impedances and check PSC or PFC indication. Test RCD timing at key points and run ramp tests when the instrument supports them. We apply adjustments if needed and always record results clearly.
You receive a certificate with traceable results and tolerances. We apply a durable label showing date, serial, and certificate number. You also get guidance on the next due date and handling tips. Your instrument returns clean, complete, and ready for site.
If you manage multiple testers, we can schedule rotations. That keeps teams working while instruments move through calibration. Our support team stays available to help with booking and logistics.
