- the power supplied by a transmitter
- the power reflected by the "feeder-antenna" unit from 2 MHz to 2.7 GHz.
Verry simple to use and extremely accurate measurement.
Excellent site or laboratory instruments, sturdy and rainproof
A shoulder bag is available to carry and protect the instruments

The ORITEL range of wattmeters for military and civil applications and for radiotelephony

ORITEL RW 501, 511 and RW 5012 wattmeters have been designed for military and civil use.
They are eminently suitable for this type of market: easy verification of installations without in vesting in sophisticated and expensive instruments. Verifications of the transmitter unit, cables and antennae or audio circuits are easy and rapid and do not require and special technical skill.
ORITEL RW 521 wattmeter for radiotelephony has been designed to enable customers to obtain information, at a lot cost, regarding the installation quality of a transmitter including its cables and antennae.
Measurements are taken directly by the installation assembly team without the presence of a qualified technician being required for acceptance purposes. The same applies to maintenance throughout the lifetime of the system, measurements can be taken quickly and easily.
As regard the parameters, both the power of the transmitter and the value of the Standing Wave Ratio (S.W.R) are measured to verify that the installation's performance conforms to expectations.
