Overview

CHD900 single phase electric ampere voltage frequency power meter coulometer is applicated for preset AC or DC current voltage range.

  • SINGLE PHASE MEASUREMENT: 3 phase measurement item is CHD9000, CHD9001.
  • LED DIGITAL TUBE DISPLAY: Three rows of 4-bit bright red LEDs simultaneously display three-phase current or voltage values or other parameters, which are intuitive and clear.
  • TRUE RMS MEASUREMENT: Adopting true RMS measurement, high precision, good stability, transformer multiplex rate can be set on-site through the instrument button, easy to use and flexible.
  • CT/PT RATE: the multiplex rate of transformer can be set on the spot by the instrument button, which is convenient and flexible to use.
