Tremetrics RA300 Series Digital Screening Audiometers
RA300 and RA300 Plus Digital Screening Audiometers
In smaller hearing conservation programs, manual audiometry testing costs you money every day. It’s time consuming for you as well as for those you test. The RA300 is a perfect solution: affordable, easy to use with minimal training, and able to deliver accurate test results automatically. The RA300 is a great fit for any hospital, family physician, community or occupational health clinic.
The RA300 Plus incorporates several additional features. With the internal memory to hold up to 64 tests and built-in talk-over capability, the RA300 Plus brings added value to your hearing conservation program. In addition, when used with the Tremetrics software packages, the audiometer becomes a fully computer controlled solution to your hearing conservation needs.
Response levels are displayed on the bright, backlit display. Automatic validity checks are built in. Random tone intervals and thresholds level between the 1000 Hz pretest and the main test to deter anticipated response patterns. Error conditions which require operator attention are noted on the readout and signaled by an audible tone.
After the test has been completed, results can be reviewed and written on an audiogram form, printed, or transferred to a computer through the RS232 computer interface.
Computer compatible, multimedia ready
The RA300 is truly versatile – it can emulate the data format of the Tracor/Tremetrics RA500 audiometer when used with many of the popular PC-based hearing conservation software programs. In addition, the RA300 Plus package* interfaces with the latest software programs that offer PC-control and monitoring of test results. This is the very first audiometer that is “multimedia” ready, including interactive, computer-voice instructed testing (patented).
Versatile output/storage choices
Menu selections, from hard copy output to digital computer files, provide a choice of formats for reporting/data transfer. The RA300 may be interfaced to most types of serial (RS232C) printers through an easy to use “Special” function. A selection of 20-column, 40-column, standard 8.5” x 11”, or A4 paper formats accommodates your portable label printer. For computer-based testing programs, an optional 64-audiogram auto-store function conveniently saves test data in the audiometer.
