Casella CEL-632 Sound Level Meter Repair
The Casella CEL-632 is an integrating sound level meter — a handheld instrument that measures and logs sound pressure level and related acoustic parameters for occupational noise, environmental, and workplace assessments. As a precision acoustic instrument, its faults concentrate in the microphone and preamp, the measurement/logging electronics, the display, and the battery.
June Company repairs and calibrates the Casella CEL-632 for occupational-hygiene and environmental-noise teams.
