Instruments for Audiology - KLD21 Diagnostic Audiometer

The KLD21 shares the same features as the KLD23 with the exception of speech and Free Field capabilities. As a result the KLD21 provides a cost-effective solution for those who need a full-featured air/bone audiometer.

Printout choices include the optional built-in thermal printer, direct connection to a laser printer, and PC connection using either NOAH or a Windows98 based Interacoustics software.
