Pulsar
Compact, hand-held, light weight, coupling-free instrument for measuring the of ultrasonic pulse velocity (UPV) of longitudinal stress waves propagating within concrete.

In contrast with traditional pulse velocity instruments, Pulsar incorporates two antenna arrays, each one with a set of 7 dry-point-contact (DPC) transducers, in order to work without a coupling material (grease or gel). The antennas are brought into contact with the surface of the test object directly which allows to make measurements much quicker. The receiving antenna is fixed to the electronic unit while the transmitting antenna is connected by a 3 meter cable.
