MECO DIT99BL-E Digital Insulation Tester

The MECO DIT99BL-E is a portable digital insulation tester engineered for accurate insulation resistance measurements in electrical systems, industrial equipment, and power distribution installations. With a test voltage of 1000 V DC and a measurement range extending up to 2000 MΩ, it is well suited for evaluating the insulation condition of motors, transformers, cables, switchgear, communication networks, and various electrical appliances. The large backlit LCD display provides clear visibility in low-light environments, while the simple push-button operation allows testing to be performed quickly and efficiently by a single user.

Designed for both field and maintenance applications, the DIT99BL-E combines measurement accuracy with practical safety features. A dedicated high-voltage warning indicator enhances operator awareness during testing, while the compact handheld design makes transportation and storage convenient. Powered by standard AA batteries, the instrument delivers reliable performance for routine inspections, preventive maintenance programs, and troubleshooting of insulation-related faults in residential, commercial, and industrial installations.
