Easy to Operate


Calibrate the AD-3253/3253B to the material to be tested, place the probe on the material and the AD-5253 displays the thickness.

Sonic Velocity Stored in Memory

Entered using the "< and >" keys. When a new entry is made, it overwrites the old one.

Low Battery Indicator

Indicator appears when battery charge is low; operator has one hour of operation remaining before requiring a new battery.

Determine Unknown Sonic Velocities

Calibrate the AD-3253 against a known test block and place probe on sample material of the same thickness. One button sets the unit to the proper thickness and the AD-3253 Automaticlly enters the correct sonic velocity.
