LANDTEK ND9A Sound Level Calibrator electrician tool

Portable Sound Level Calibrator

The LANDTEK ND9A is a handheld calibrator designed for technicians who need to verify the accuracy of sound level meters and dosimeters before field measurements or laboratory sessions. It provides a stable acoustic reference so that microphones can be sensitivity-checked on site without returning equipment to a calibration laboratory.

Single Fixed Reference Level

The unit generates one calibrated sound pressure level and frequency, so it cannot accommodate meters that require multi-point or multi-frequency verification. Users must confirm that their instrument’s specification matches the calibrator’s single output before relying on it for compliance work.

Red Rugged Enclosure

A compact red housing protects the solid-state circuitry from knocks and dust during transport between job sites. The calibrator ships in a single box with a three-year parts and one-year labour warranty period, indicating the manufacturer expects the device to withstand regular field handling.
