NANAO ELECTRIC Manufacture NAWSL Water-cooled Generator Insulation Tester

Product introduction

This instrument designed for the measurement of water cooled generator test, also can be used to insulate the laboratory or field test trials. Output current is more than 25mA. The maximum output voltage is 2500V. Includes high-precision micro-current measurement systems, digital boost system. Just use a high-tension line and a signal line connected to the sample can be measured. Automatic measurement, results from the large-screen LCD, and the results are stored.

Also called name

Water cooled generator insulation resistance tester, water cooled generator tester, insulation resistance tester

The Characteristics of the products

1. 32-bit micro-controller, easy to operate.

2. Automatically calculate the absorption ratio and polarization index, and automatically store 15 seconds, 1 minute, 2 minutes, 10 minutes to facilitate the analysis of data per minute.
