BA-202-25
The TSI BA-202-25 is a bio-acoustic simulator for daily audiometer verification, capable of performing OSHA level verifications. This device lets you perform daily audiometer checks without the need for a human test subject. The unit can be used as a portable tabletop unit or can be mounted on the wall.
- Test frequencies 125 Hz to 8 kHz
- 9V alkaline battery or 120V/220VAC current with optional adapter
- Low battery indicator to avoid service interruption
- 10-foot microphone cable facilitates mounting options other than standard in-room wall mounting
- CE approval
