Svantek SV 33B Class 1 Sound Calibrator

Svantek SV 33B Class 1 Sound Calibrator

The SV 33B is the practical current Class 1 acoustic calibrator for consultants, occupational hygienists and sound-measurement teams who need a precise 114 dB reference at 1 kHz. It is designed for verifying Class 1 and Class 2 sound level meters and noise dosimeters fitted with 1/2-inch microphones.

Who should choose SV 33B?

Choose SV 33B when your routine work uses 1/2-inch microphones and a single 114 dB field-check level is sufficient. It is a strong fit for cost-conscious occupational noise, environmental noise and building-acoustics teams that want Class 1 calibrator accuracy without the additional dual-level and 1/4-inch flexibility of SV 36.

Key features

• Class 1 accuracy compliant with IEC 60942:2017, subject to applicable documentation.
• 114 dB reference level at 1 kHz.
• Automatic signal adjustment using internal reference, pressure and temperature sensors.
• Compatible with 1/2-inch microphones used by sound level meters and dosimeters.
• Robust portable housing for field and laboratory verification.

Specification summary

• Class: Class 1 acoustic calibrator.
• Reference: 114 dB at 1 kHz.
• Microphone compatibility: 1/2-inch microphones.
• Standard: IEC 60942:2017, subject to applicable documentation.

Applications

Use before and after occupational noise surveys, environmental sound measurements and building-acoustics assessments to check measurement equipment.

SV 33B or SV 36?

SV 33B is the focused single-level choice. Select SV 36 when you need both 94 dB and 114 dB levels, 1/4-inch microphone compatibility, automatic microphone detection, broader instrument coverage and type-approved dual-range performance.

What it solves

It gives Malaysian measurement teams a straightforward current reference source for routine verification of 1/2-inch Class 1 and Class 2 acoustic instruments.
