Casella CEL-632C Sound Level Meter TSI

Model Number: CEL-632C1 | Advanced Sound Level Meter with 1/1 and 1/3 Octave Band Analysis

Casella CEL-632C Sound Level Meter TSI is a premium, all-in-one instrument designed for detailed occupational noise assessments and industrial noise analysis. Built with a user-friendly interface and rugged construction, this model combines the features of the CEL-632A and CEL-632B with the added capability of both 1/1 and 1/3 octave band analysis—making it an ideal solution for professionals in environments where precision and compliance are essential.

Compliant with ISO 9612 and OSHA 29CFR 1910.95 standards, the CEL-632C supports advanced noise evaluations, including the identification of specific frequency components and accurate hearing protection selection. All key noise parameters—such as LEQ, LAVG, and LPeak—are measured and stored simultaneously, ensuring that no essential data is missed during a measurement session.

With a wide measurement range up to 140 dB and no need for manual range switching, the CEL-632C simplifies setup and operation. The high-contrast display can be configured to show simplified or detailed views, depending on user preferences. The device supports data markers, back erase, and up to 60 hours of audio recording for source identification. Users can also record voice notes directly on the device for later reference.
