In the Laboratory or in the Field
Take Highly Accurate Measurements
Even in Tough Temperature Conditions

Severe temperature environments, such as engine rooms withintense temperature changes and constant temperature rooms,
can hinder high accuracy measurements. Hioki provides alineup of high-accuracy through-type and high-accuracy
clamp-type current sensors with excellent temperature
characteristics and wide operating temperature ranges.
The PW3390 can operate from a low temperature environmentof −10°C to a high temperature of 40°C, allowing you to take it
to measure in various environments.

Achieve High Accuracy Measurement
Even in the Field

Dramatically compact and light-weight form factor achievedby concentrating the calculation functions in the power
analysis engine. Highly accurate measurements normallyachieved in the laboratory are now also possible in the field.

External Power Supply Not Needed for
Sensor Connections
