Feedbacks
From Spain
I am very satisfied with the RD6000A delta tan meter. Frequency conversion technology and clean power supply make measurements extremely accurate.
From Ukraine
The RDZHF-709B SF6 comprehensive tester is so great! It’s efficient, combining humidity, purity, and decomposition product tests all in one device. And the results are really accurate.
From UK
The Six-Phase Relay Protection Tester is an impressive and highly versatile device. Its ability to output six-phase voltage and current makes it ideal for a wide range of testing scenarios, from traditional setups to advanced three-phase transformer differential testing. It’s really Good!
From Kenya
The functions of this ultra-low frequency dielectric loss tester are very powerful, equivalent to: ultra-low frequency withstand voltage test, insulation resistance test, dielectric loss test, partial discharge test, and DC high voltage leakage current test.
From Ethiopia
I am very satisfied with the RDTBT series transformer test bench. It is easy to operate, with a clear digital display, and the test results are really concise. It greatly improves testing efficiency and reliability.
From Vietnam
We have previously purchased our CT PT Analyzer and six-phase relay protection tester and are very satisfied with the quality and after-sales service of Redo. Recently, we are inquiring about the price of 15KV insulation resistance tester, dielectric response analyzer and 500KV series resonance device.
