Product Introduction

The Holaday HI3604 power frequency field strength meter from the United States is mainly designed to detect electromagnetic field strength, with high accuracy, easy use, and simple operation.






HI-3604 is designed specifically for detecting the electromagnetic field strength around 50/60Hz power lines, electrical equipment and facilities, video display terminals, etc. It provides accurate testing tools for electrical environments for engineers, industrial hygiene scholars, and personal safety and health experts.
The unit displayed on the LCD monitor can be selected from milliGauss, Gauss, volts/meter, kilovolts/meter, and has graphic display function, which can conveniently and intuitively locate the position of the electromagnetic field source and strong radiation points.
The single probe achieves full range, and the instrument panel is designed with laminated buttons, which is very suitable for on-site use. The internal memory can store up to 127 readings.



All functions and range selection can be achieved through the laminated button on the front panel, and the internal electronic control switch automatically selects the required range for electric or magnetic field measurement.
The biggest feature is the ability to store and display large amounts of data.

Amplitude response: The true root mean square method accurately measures the field quantity of non sinusoidal waveforms.
Polarization response: Electric field sensors and magnetic field sensors are used to measure the polarization component of a single field at a certain moment.
Power supply: Two 9V alkaline batteries (NEDA1604A, Duracell MN1604 or similar)
Output: LCD display; The preamplifier output of the earpiece jack (analog signal of the sensor/amplified to 1mV; digital fiber signal connected to HI-3616 for remote control).
