SM-CAL1 - Sound Meter Calibrator The Amprobe SM-CAL1 is a sound meter calibrator with two output levels of 94 dB and 114 dB. The calibrator generates these fixed sound level signals for calibration of sound level meters. The unit ships with a ½" adaptor installed to accommodate sound meters and microphones with ½ diameter.

SC-05 - Sound Level Calibrator 94dB and 114dB Sound Calibration at 1kHz 2.Accurate and simple to use 3.Fits 1/2”diameter microphone

SCAL1356 - Sound Level Calibrator Conforms to ANSI S1.40-1984 and IEC0942:2003 Class 2. Calibration Levels of 94dB and 114dB. Fits 1", 1/2" and 1/4" diameter microphones. Internal Battery Test.

72-7260 - Sound Level Meter Calibrator Specifically intended for Tenma #72-6635 and #72-860 Sound Level Meters, this precision calibrator is compatible with any instrument with a 1/2" diameter mic element housing. Essential for maintaining the accuracy of any portable sound level meter, this unit generates a precise 1KHz tone, at exactly 94dB. Single slide switch provides on/off/battery test functions.

1562-A - Sound Level Calibrator The 1562 Sound Level Calibrator is a self contained unit for making accurate filed calibrations on microphones and sound measuring instruments. It generates a precisely known sound pressure level at five ANSI-preferred frequencies. With its several frequencies, improved accuracy and built in oscillator, the 1562 Sound Level Calibrator outperforms all other sound level calibrators.

DSL 336 - Sound Level Calibrator 94dB and 114dB Sound Calibration at 1KHz. Accurate and Simple to use. Fits 1", 1/2" or 1/4" diameter microphone

05000 Sound Level Calibrator Calibration sound source for microphones and sound measuring systems. Sound pressure level: 94 dB (1 Pa).
Frequency: 1000 Hz.

GA601 - Single Level Sound Meter Calibrator The Castle GA601 produces a calibration tone of 1000Hz at a level of 94dB re 20µPa at the microphone.

DVM1356 - SOUND LEVEL CALIBRATOR 114dB & 94dB at 1kHz * calibration levels of 94dB and 114dB * output frequency: 1kHz * suitable for microphones with diameter 1", 1/2" and 1/4" * comes with 1/2" and 1/4" microphone adapters

3541 - Sound Intensity Calibrator, with p, I and v level and Residual p-I Index Type 3541 enables calibration of intensity measuring instruments by using a coupler designed especially for sound intensity calibrations. Intensity-probe microphones are positioned in the coupler which, in conjunction with a pistonphone, simulates a plane sound wave propagating along the axis of the probe.

CAL73 - Sound Level Calibrator The CAL73 sound level calibrator is used to calibrate sound level meters and other sound measurement equipment. You can calibrate 1 inch diameter microphones directly and 1/2 inch microphones using 1/2 inch adaptor supplied with the calibrator.

TM 100 - Sound Level Calibrator Standard Sound rigging values are 94dB and 114dB. * 1/2" microphone adapters provided. * With low battery indictor.
