Reliable, fast and accurate calibration


Located within 5 minutes of M1 J5, and 10 minutes from M25 J19, Martindale Electric’s calibration service gives you a reliable service and fast turnaround. Most instruments are calibrated in-house and ready within 3 – 5 days. Our capabilities allow us to calibrate a wide range of electrical, environmental and mechanical test equipment.

All our calibration certificates are traceable to UKAS national standards, via certificates held for all our calibration instruments. Our centralised computer system allows us to store calibration data indefinitely, and quickly locate previous calibration results. Should you ever misplace your calibration certificate we can easily email a copy to you at no extra cost.

Collection and delivery of your items can be arranged through our courier – DPD. If you contact us before 12pm we can normally collect the same day. Carriage is FREE when returning 5 or more items.
