Nor1290 sound intensity probe

The Nor1290 is the Norsonic intensity probe for the Nor150 sound level meter.​

The probe head has two adjustment knobs. The uppermost knob is for compensating spacer distance and center displacement, while the lower is for locking the probe firmly into an angle. The angular adjustment has well-defined mechanical steps for your convenience.

The detachable probe head is equipped with a standard 7-pin lemo connector with firm attachment via a screw-lock. It may be connected directly to the top of the Nor150, extended via a standard microphone cable or mounted on top of the probe handle rod. This ensures maximum flexibility and gives you full configuration freedom, while keeping the cost of additional equipment such as extension cables to a very minimum.
