Hioki Launches Clamp On Power Logger PW3365-20

Nagano, Japan

Hioki is pleased to announce the launch of the Clamp On Power Logger PW3365-20, the world''s first instrument capable of measuring power safely and accurately without requiring the operator to make contact with a metal conductor.

Hioki developed the PW3365-20, the world''s first power meter to allow operators to measure voltage safely and accurately simply by clamping a sensor around an insulated wire, in response to the needs of customers who wish to measure power more safely. By equipping a power meter with a non-contact voltage sensor, the company has made it possible to avoid the risk of short-circuits and electric shock when measuring voltage by conventional means.

Currently, many companies are working to save energy, creating new opportunities for measuring power consumption. In the past, power measurement in settings such as large factories was overseen by workers with electrical knowledge and experience. However, as companies across the entire spectrum of sizes and industries are driving up the need for power measurement, such measurement is being increasingly carried out by workers who lack adequate knowledge and experience. Consequently, demand for products that enable power to be measured safely has been rising. Against this backdrop, Hioki began developing a new product that takes a new approach to power measurement.

Clamp-style power meters have entered into widespread use in the field of power measurement. These instruments already had the ability to measure current using clamp-on sensors, allowing measurements to be made safely from outside insulated wires. However, operators have typically had to connect clips to the metal terminals of circuit-breakers or other components in order to measure voltage. This approach poses the risk of a short-circuit if the technician mistakenly allows one of the metal clips to come into contact with the adjacent metal terminal as well as the risk of electric shock if he or she inadvertently touches an exposed metal conductor.
