Norsonic, RION, CESVA

N-1251, -1252, -1253
Self Compensating Precision Acoustic Calibrator

Fully certified as traceable to international standards

• Automatically adjusts for changes in the load volume applied to the calibration cavity, thereby removing the need for manual correction of the level for the effective volume of different types of microphone.
• Compensates for changes in temperature, humidity, and barometric pressure to remove the need for manual corrections for these parameters. 
• Output level 114 dB at 1 kHz. Meets the requirements of IEC 942 Class 1.
• N-1252 Class 2.
• N-1253 Class 1 or Class 0.
  (250 Hz or 1000 Hz), 124 dB

NC-74
Sound Calibrator

The NC-74 is a sound calibrator conforming to IEC 60942, Class 1 requirements, suitable for calibrating high-precision sound pressure level meters.

• Compact dimensions and light weight
• Two alkaline batteries (IEC LR6) will power the unit for over 30 hours continuous use.
• No need for atmospheric pressure compensation

NC-72
Pistonphone 

Portable sound source for calibration of sound level meters and sound measuring system. Sound pressure level 114 dB ± 0.2 dB. Frequency 250 Hz ± 1%. 

SAW CA111 is a small sound source for calibrating measurement microphones, sound level meters and other sound measurement equipment. The calibrator can be used on 1/2-inch and 1/4-inch microphones with adapter. It conforms to IEC 60942:2003 Class 1, ANSI S1.40-1984 and GB/T 15173-1994.

CB004 - Class 2 acoustic calibrator

Portable, user friendly calibrator, ideal for checking sound level meters and dosimeters on the measurement site, or in the laboratory.

It is designed especially to check class 2 dosimeters and sound level meters.

Represents a cost effective yet accurate means of checking, before and after the measurement.

May be used with any microphone suitable for closed coupler checking and of ½" diameter.

Complies with norm IEC 60942:2003 class 2.

Field Calibrators: Vibration

RION, MMF, EXTECH

VE-10
Accelerometer Exciter 

Handy vibration source for calibration of vibration meters and accelerometers. Acceleration 10 m/sec², velocity 10 mm/sec, displacement: 10 mm, frequency 159.2 Hz. 

New Vibration Calibrators

The VC 21 has unique properties. It provides 7 selectable frequencies with up to 5 magnitudes each. Its lowest frequency of15.915 Hz extends the range of application to the calibration of, for example, whole-body vibration meters to ISO 2631 / ISO 8041and building vibration meters to DIN 4150.
