Nor150 intensimétrie

homologué classe 1

The Nor150 fitted with sound intensity option and the sound intensity probe kit Nor1290 is a powerful tool for all type of sound intensity measurements. It is designed for easy use in all type of measurement conditions.

The remote control handle using a Smartphone as a measurement control and displaying device forms a light weighted and easy to use system, allowing the user to perform all measurements with a single hand operation. The Smartphone communicates via WiFi with the internal web server running in the Nor150. The system may also be used with the sound intensity probe directly attached to the Nor150.

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.
