The high-end sound calibrators 4010 and 4011
4010
Sound Calibrator
Class 1 according IEC60942
- frequencies 250 Hz and 1000Hz
- sound pressure levels 94 dB and 114dB
- microphones 1“, 1/2“ and 1/4“
- PTB Type-examination Certificate
The 4010 is a sound calibrator conforming to IEC 60942 class 1 and ANSI S1.40 for the calibration and the verification of microphones and sound level meters.
The combination of two sound pressure levels and two frequencies allow both level linearity and frequency linearity to be verified.
Each sound calibrator is supplied with an individual calibration certificate.
The reference microphone and control circuit together maintain a constant sound pressure level inside the calibration coupler and automatically adjust for changes in load volume, temperature, atmospheric pressure and relative humidity.
In addition the sound calibrator measures the environmental conditions temperature, atmospheric pressure and relative humidity
4011
Sound Calibrator
- Class 1 according IEC60942
- frequency 1000 Hz
- sound pressure level 114 dB
- microphones 1/2“ and 1/4“
The 4011 is a sound calibrator conforming to IEC 60942 class 1 and ANSI S1.40 for the calibration and the verification of microphones and sound level meters.
It generates a sound pressure level of 114 dB at a frequency of 1000 Hz for the verification of the calibration of sound level meters.
Each sound calibrator is supplied with an individual calibration certificate.
The reference microphone and control circuit together maintain a constant sound pressure level inside the calibration coupler and automatically adjust for changes in load volume, temperature, atmospheric pressure and relative humidity.
The sound calibrator can be used for 1/2“ and 1/4“ microphones.
Acoustic measurement technology since 1928
The Microtech Gefell GmbH is manufacturer of high quality, handmade measurement and studio microphones founded 1928 by Georg Neumann.
Besides the company offers calibration and services for all manufactured products.
The Measurement technology includes 1“, ½“ and ¼“ measurement capsules, measurement preamplifiers for different connection techniques (Conventional Lemo, ICP®, Phantom P 48 XLR, Digital USB AES 42 XLR), outdoor and environmental microphones, microphone arrays, sound intensity probes, power supplies, calibration devices as well as turnkey solutions (e.g. special test benches for car acoustics).
