HIOKI Clamp On Power Meters are multi-channel power measuring devices utilizing clamp sensor input to accurately and safely measure power on single-phase to three-phase lines. The PW3365-20 takes safety and convenience one step further by being the world’s first non-metallic contact power meter that utilizes completely covered voltage clips that can be attached to any part of a cable or busbar. Customers can now monitor power demand and other power parameters to aid in energy audits and validate energy-saving measures without risk of short-circuit accidents, power interruptions, or bodily injury due to electrocutions. Clamp On Power Logger PW3365-20 by itself does not support current and power measurements. Current and power measurements require clamp-on sensors, sold separately. Use only HIOKI SD cards guaranteed to work for saving measurement data (options, sold separately).

Key Features
● Eliminate the risk of short-circuits and electrical accidents
● The world’s first instrument to offer no-metal-contact power measurement
● Measure in potentially hazardous locations
● Free yourself from the risk of short-circuits by measuring right on the cable sheath without ever needing to touch metal to energize parts
Measurement Principles of the World’s First Non-contact Voltage Sensor
The Voltage Sensor PW9020 used by the PW3365-20 is able to perform non-contact measurement by means of the principle described below. Inside the PW9020 is a metal plate that serves as an electrode, and when this electrode detects a voltage (potential difference) in the object being measured, a minuscule current flows to it. By generating a voltage such that this current is eliminated, the sensor can accurately measure the voltage in the conductor.
