VOLTCRAFT ET-400 Insulation tester 250 V, 500 V, 1000 V, 2500 V 2.5 TΩ

The VOLTCRAFT ET-400 insulation tester is a highly precise measuring instrument for professional insulation tests up to 2500 V. With a wide measuring range of up to 2.5 TΩ and compliance with the CAT IV 600 V measuring category, it is suitable for Ideal for demanding analyzes on electrical systems and operating materials.

Versatile test voltages and measurement ranges
The device offers four firmly defined test voltages of 250 V, 500 V, 1000 V and 2500 V. These can be adjusted in precise steps of 10 % of the range, in order to exactly meet specific test requirements.

Extensive analysis functions
In addition to pure resistance measurement, the ET-400 supports PI (polarization index) and DAR measurements (dielectric absorption ratio). An integrated comparison function as well as timer measurements enable an efficient evaluation of insulation states conforming to the standards.

Clear display and documentation
All measured values are clearly shown on a large, 12.95 cm (5.1 inch) LCD display with background lighting. The internal data memory offers space for up to 999 groups that can be analyzed in detail via the USB interface and the accompanying PC software

High safety standards
To ensure safe operation, the measuring device features high-voltage alarm and an automatic discharge function after measurement. The robust design and the classification in CAT IV 600 V ensure maximum protection for the user when working at the source of the low-voltage installation.
