Portable Audiometer
Calibration System
Type i714
PRODUCT DATA
The i714 Portable Audiometer
Calibration System is an easy,
flexible and reliable solution for
automated calibration of audiome-
ters to IEC and ANSI standards.
Audiometer certification is the
primary focus, but the system is
designed to accommodate the
everyday needs of hospitals and
clinics as well as those of calibra-
tion and metrology laboratories.
Other fields of use are audiometer
R&D and factory production test-
ing.
The system is build around the
powerful sound level meter and
analyzer Type 2250. It utilizes the
precision of the Class 1 measuring
instrument, experience in calibra-
tion and simplicity of use. The
system performs the tasks rang-
ing from basic standard audiome-
ter testing with fully automated
procedures to advanced custom-
ized tests.
The Type i714 with integrated
database takes care of test proce-
dure execution as well as all
house-keeping data including cli-
ent e-mail reminder for next cali-
bration.
The calibration Software is not
limited to any specific brand or
