“I work for a local school district with thirteen schools and about 16 audiometers.  We have the audiometers sent to one location.  When received I call Foster Special Instruments and set up an appointment to have the calibration checked.  Our last day of school was June 4th, machines were calibrated on June 19 and the invoice was received on June 22.  This system was suggested by Foster Special Instruments.  Since the school nurses don’t work summers, we can have their equipment replaced, repaired or calibrated and back in the Health Rooms before the first student comes through the door for a new school year.”

-Rose F.
