MECO DIT 954 Digital Insulation Tester
The MECO DIT 954 is a 5 kV digital insulation tester capable of measuring insulation resistance up to 200 GΩ while also providing AC voltage, phase sequence, and phase status testing functions. Its backlit display, safety features, rugged construction, and comprehensive accessory kit make it a practical solution for electrical maintenance, commissioning, and troubleshooting tasks.
Description
The MECO DIT 954 is a professional-grade digital insulation tester designed for evaluating the insulation integrity of electrical systems, equipment, and installations. With selectable test voltages up to 5 kV and insulation resistance measurement capability up to 200 GΩ, it is suitable for testing transformers, motors, cables, switchgear, generators, power capacitors, and other high-voltage electrical assets. Its large backlit LCD display, straightforward push-button operation, and automatic ranging function help technicians perform measurements efficiently in both field and industrial environments.
In addition to insulation resistance testing, the DIT 954 offers AC voltage measurement up to 600 VAC, phase sequence verification, and phase status indication. The instrument incorporates a high-voltage warning LED, reverse-voltage protection circuitry, and IP44-rated protection for enhanced reliability and user safety. Battery or AC adapter operation provides flexibility for on-site maintenance, commissioning, troubleshooting, and preventive testing applications.
