Description

The EMR-300 Meter features a lightweight design with an
integral shock resistant cover. Customers utilize this
meter for high sensitivity andhighdynamic range surveys.
Electric, Magnetic and shaped probes are available to sat­isfy virtually every survey need. Every probe available has
approximately 60dB of dynamic range, without changing
measurement ranges. Unique to this series are H-field
probes available from 3 kHz to 1 GHz.

All other specifications are the same. This lightweight me­ter provides simple operation. All probes are automati­cally detected at turn-on, and automatically “zeroed”,
even while immersed in an RF field. At six-minute intervals,
this meter re-zeroes itself without operator intervention.
The EMR-300 is supplied with the EMR-TS software and
data transfer package. This includes 2meter and 20 meter
fiber optic cables that allow bi-directional communication
from your computer to the EMR meter.

The EMR-300 has the ability to store readings and also
has time and spatial averaging capabilities. Spatially aver
aged limits are the basis for almost all international stan
dards or guidance’s. For readings of averaged fields such

as vertical scans over the height of the body, or time
averaged readings in front of a rotating radar, averaging is
almost always required to properly assess the whole body
limits.

Data logging is an additional feature of the EMR-300. Be­ing able to store readings can be a time saving, important
method of documenting your survey. Data is stored with
time-of-day information so that you can tie readings di­rectly to the date and time of your survey.

The probes compatible with the EMR-300 are available as
calibrated (“C”) or non-calibrated versions. See pages
48-51 for more details.

The EMR-300 is supplied with a case that holds the meter,
manual, charger and multiple probes (available probes
are listed on pages 48-51). The EMR-TS software and ca
ble system is also supplied as standard, which consists of
the software, 2 and 20 meter fiber optic cables and an
adapter to convert the fiber optic signals to a common

­9-pin serial connector. All EMR meters and probes have a

­two-year warranty and calibration interval.
