About Digital Insulation Testers
CIE digital insulation testers provide direct numerical readout of insulation resistance on a backlit LCD display, eliminating the parallax-reading uncertainty of analog instruments. They incorporate advanced test functions including dielectric absorption ratio (DAR) and polarisation index (PI) measurement — important for assessing the condition of motor windings and large power equipment insulation. Test voltages range from 500 V (DIT-5005) up to 5000 V (DIT-5000), covering the full range from low-voltage equipment testing to HV cable and transformer insulation assessment.
The DIT-2500 also functions as a digital multimeter, making it a versatile instrument for electrical engineers who need both insulation testing and general electrical measurement in a single handheld unit. The DIT-5000 covers insulation resistance up to 200 GΩ with auto-ranging, making it suitable for testing very high-quality insulation systems in cables, power transformers, and rotating machines.
Digital insulation testers are widely used by electrical testing laboratories (NABL accredited), power utility maintenance teams, commissioning engineers, and industrial electrical departments. CIE supplies digital insulation testers throughout India — Kolkata, Howrah, Bhubaneswar, Bangalore, Chennai, Hyderabad, Mumbai, Delhi, and all major industrial and power sector locations.
