Suparule, the manufacturer of measuring instruments, has made available its new C60 electrical tester. The patented product is designed as an all-in-one tester, measuring voltage, resistance and current. The product is a result of a joint venture with the Taiwanese instrument manufacturer, APPA. The instrument will be distributed through City Electrical Factors Group, which has almost 400 retail outlets in Britain. SupaRule's shares are listed on AIM in London and DCM in Dublin.
