Thread: METRA Digital insulation resistance tester

METRA VI has introduced DIT-99 series battery-cum-mains operated digital insulation resistance testers for Rs 1200 only. These CPU controlled instruments change 6V into 100V j250V j 500V j1000V DC voltage by using a DC voltage converter with low power loss and high change rate. The testers can work off 50Hz, 230V AC or four l.5V AAA-size batteries. Voltage options available are 100V (DIT99A), 250V (DIT-99B), 500V (DIT-99C) and 1000V (DIT-99D). The testers are suitable for on-site maintenance of escalators, electric and mechanical equipment as well as telecommunication equipment.
