Try Celtek Electronics think they,re in Preston but I’ll put the details on the site tomorrow. They’ll do an estimate if requested and can also calibrate if required. They also keep quite abit of stock and second hand parts for older test equipment. This is particularly helpful because from experience AVO/Megger seem no longer able to repair anything thats more than a couple of years old. We use them for all our test equipment, a helpful company that does the business. Dave I’ll call you direct tomorrow when Im back to work with all the details.
Celtek, we use them to recalibrate our microwave monitors, it looks as if they have three different companies under the Celtek name. Celtek Maunfacturing are in Liverpool, Celtek Calibration are in Blackpool and Celtek Electronics in Southport.
