Description
Overview
GAOTek three-channel monitoring designed and manufactured for on-site simultaneous monitoring and recording 1 to 3 channel AC current or leakage current, it is composed of recorder host, current clamps, charger, monitoring software and communication cable, etc. Widely used in 380/220 v power system, provide safe, accurate and convenient power instrument for power inspectors. Host adopts LCD display, three channels with the same screen display, clear at a glance, there are Chinese and English operation interface two choices, suitable for different countries of engineering and technical personnel. The recorder is equipped with a large capacity rechargeable lithium battery, displays power energy with a three-grid mode, which can continue recording for up to 7 days. With the function of system clock and super storage space, it can set the monitoring and recording time on site, can store 200,000 sets of data, and has the function of setting the interval time of automatic storage, setting from 1 to 99 minutes. Monitoring software has online real-time monitoring and historical query functions, historical data reading, consulting, saving, reporting and other functions. The current clamp is made of Permalloy and adopts CT technology and unique double layer magnetic shielding technology. It is almost unaffected by the external magnetic field, which ensures uninterrupted monitoring for a long time with high accuracy, stability and reliability.
