ZC7122D/7120D series programmable withstand voltage/insulation resistance tester

The ZC71 (D) series AC and DC withstand voltage/insulation testers are the upgraded products of the company's ZC71 series products. The instrument uses linear amplification technology to produce a low-distortion sine wave output, making the test more accurate. The use of a 4.3-inch color LCD screen and a user-friendly interactive operation mode make it clearer and easier for users to understand. The test results and test conditions are displayed at the same time, which makes users feel at ease about the test conclusions. The instrument can be widely used in fields that require safety testing.

Brief introduction

The ZC71 (D) series AC and DC withstand voltage/insulation testers are the upgraded products of the company's ZC71 series products. The instrument uses linear amplification technology to produce a low-distortion sine wave output, making the test more accurate. The use of a 4.3-inch color LCD screen and a user-friendly interactive operation mode make it clearer and easier for users to understand. The test results and test conditions are displayed at the same time, which makes users feel at ease about the test conclusions. The instrument can be widely used in fields that require safety testing.
