FEATURE TEST & MEASUREMENT One tool for environmental measurements
Flir Systems has announced the new multi-purpose EM54 environmental meter for HVAC/R measurements
T
he EM54 is ideal for inspecting ducting, electrical motors, thermal
equipment, and other system components in residential, commercial,
and industrial facilities. This high quality, easy to operate meter can help users quickly and accurately identify symptoms of clogged filters, duct leaks
that reduce airflow, and overloaded HVAC systems. Equipped with an external vane anemometer for wide range, high resolution air velocity measurements, the Flir EM54 environmental meter lets users check air speed at duct inlets and outlets quickly and precisely. This allows for simplified duct airflow calculation and efficient troubleshooting.
HYGROMETER The EM54’s built-in hygrometer identifies deviations from ambient relative humidity levels, which can cause static hazards at manufacturing sites and discomfort in homes and offices. The included Type-K contact temperature probe is useful for checking electric motors and thermal equipment components for proper operating temperatures. The EM54 also calculates wet bulb and dew point temperature. The environmental meter features an easy to read, multi-function display, a MIN-MAX-AVG recording function, and a programmable auto power off timer. Rugged and reliable, the multi-purpose
diagnostic tool comes with a three-year limited warranty.

New touchscreen power meter launched With the new R&S NRX RF power meter, even complex test setups can be configured quickly
R
ohde & Schwarz is launching the R&S NRX on the market so that
users can transparently configure their measurements and perform them conveniently. The R&S NRX even makes it possible to perform triggered and synchronised multichannel measurements with different power sensors. The user operates the instrument
via the integrated high resolution five inch touchscreen, and measurements are configured using large buttons. The system supports the user with a
logical calibration and draws attention to conflicts in case of doubt. If required, the instrument can also be operated using the buttons on its front panel.
The R&S NRX comes as standard
with two robust sensor ports, which can be optionally upgraded to four. In addition, sensors can also be connected via USB or ethernet.

The user can connect all terminating power sensors from the Rohde & Schwarz portfolio to the sensor connectors. The R&S NRX-B9 sensor interface module integrates the directional power sensors of the R&S NRT-Z family into the measurement to determine power in both transmission directions. With the optional R&S NRX-B1 sensor check source module, users can test
sensors for a pending measurement. The high- precision 50 MHz/1 GHz reference generator module generates continuous
wave signals as well as pulsed steep slope signals.
The R&S NRX power meter is
available now from Rohde & Schwarz, and will soon be available from select distributors. The R&S NRX is superceding the proven R&S NRP2 power meter.
