Accurate measurement

3274 Cygnus Instruments says that its Cygnus 4 general purpose, multiple echo depth gauge offers greater measurement accuracy than previous models. The new unit is said to be easy to use with a three button keypad and automatic probe recognition for accurate optimisation. Other features include a minimum thickness alert, echo strength indication, display freeze and a deep coat mode to allow measuring through coatings up to 20mm thick.

The LCD graphic display has an automatic, white back light, displays sound velocity, probe type and battery status and is enclosed in a durable aluminium casing. Highly versatile, the unit can be used in all typical metal thickness inspections such as safety checks on steel bridges and street lighting columns.
