NIM-511 Industrial Radiation Field Meter

NIM-511 Industrial Radiation Field Meter Overview

Designed to make measurements a simple process, the Narda Model NIM-511 combines an unprecedented ease of operation with powerful measurement capabilities.

It provides the industrial plant manager and safety professional with an accurate and inexpensive solution for proving compliance with regulations that cover exposure to RF radiation. The NIM-511 model provide a complete measurement system comprised of an extremely easy to operate meter and a probe that contains sensors to measure both the electric (E) and magnetic (H) field components of an electromagnetic wave.

There is no need to change probes to measure the electric and magnetic fields as the probe contains two sets of sensors that seperately measure each field. Simply press the E/H Field key combination to change the field that you want to measure.

The Narda Safety Test Solutions NIM-511 Industrial Radiation Field Meter is available at all Air-Met offices for sale only.

Features

NIM-511 Industrial Radiation Field Meter Features

Complete Measurement System with Dual Electric and Magnetic Field Probe for Frequencies up to 100 MHz
There is no need to change the probes as the probe contains two sensors that seperately measure each field.
Covers Most Industrial Equipment
Measures both the electric and the magnetic field components (E and H fields) for equipment operating below 300 MHz. The NIM-511 has a much broader sensor than the NIM-513 Meter that operates from 300 kHz to 100 MHz and is adjusted to
the reference calibration frequency at 13.56 MHz.
No confusing scales. Simply read the digital display including the unit of measurement
No difficulty zeroing with the Auto Zero executed repetitvely every 15 minutes
Fast and Reliable Measurements
Extremely Easy to Use
Low Cost, Compact and Lightweight
