Ambco Audiometers was established in California, United States of America, in 1941, even earlier than 1945, which is the earliest year that this web site allows us to list on our profile. Our service is unequaled, as we calibrate and/or repair all makes of audiometers and return them to our customers as quickly as possible. We also ship from stock, and respond to all calls within 24 hours. Our products are state of the art, and there are currently four models to choose from, along with two packages of amazing value. Additional accessories are also available.
